        Args:
            parent (str): Name of the organization to groupBy. Its format is
                "organizations/[organization\_id]".
            group_by (str): Expression that defines what assets fields to use for grouping. The
                string value should follow SQL syntax: comma separated list of fields.
                For example:
                "security\_center\_properties.resource\_project,security\_center\_properties.project".

                The following fields are supported when compare\_duration is not set:

                -  security\_center\_properties.resource\_project
                -  security\_center\_properties.resource\_type
                -  security\_center\_properties.resource\_parent

                The following fields are supported when compare\_duration is set:

                -  security\_center\_properties.resource\_type
            filter_ (str): Expression that defines the filter to apply across assets. The
                expression is a list of zero or more restrictions combined via logical
                operators ``AND`` and ``OR``. Parentheses are supported, and ``OR`` has
                higher precedence than ``AND``.

                Restrictions have the form ``<field> <operator> <value>`` and may have a
                ``-`` character in front of them to indicate negation. The fields map to
                those defined in the Asset resource. Examples include:

                -  name
                -  security\_center\_properties.resource\_name
                -  resource\_properties.a\_property
                -  security\_marks.marks.marka

                The supported operators are:

                -  ``=`` for all value types.
                -  ``>``, ``<``, ``>=``, ``<=`` for integer values.
                -  ``:``, meaning substring matching, for strings.

                The supported value types are:

                -  string literals in quotes.
                -  integer literals without quotes.
                -  boolean literals ``true`` and ``false`` without quotes.

                The following field and operator combinations are supported: name \| '='
                update\_time \| '>', '<', '>=', '<=', '=' create\_time \| '>', '<',
                '>=', '<=', '=' iam\_policy.policy\_blob \| '=', ':'
                resource\_properties \| '=', ':', '>', '<', '>=', '<=' security\_marks
                \| '=', ':' security\_center\_properties.resource\_name \| '=', ':'
                security\_center\_properties.resource\_type \| '=', ':'
                security\_center\_properties.resource\_parent \| '=', ':'
                security\_center\_properties.resource\_project \| '=', ':'
                security\_center\_properties.resource\_owners \| '=', ':'

                For example, ``resource_properties.size = 100`` is a valid filter
                string.
            compare_duration (Union[dict, ~google.cloud.securitycenter_v1.types.Duration]): When compare\_duration is set, the GroupResult's "state\_change"
                property is updated to indicate whether the asset was added, removed, or
                remained present during the compare\_duration period of time that
                precedes the read\_time. This is the time between (read\_time -
                compare\_duration) and read\_time.

                The state change value is derived based on the presence of the asset at
                the two points in time. Intermediate state changes between the two times
                don't affect the result. For example, the results aren't affected if the
                asset is removed and re-created again.

                Possible "state\_change" values when compare\_duration is specified:

                -  "ADDED": indicates that the asset was not present at the start of
                   compare\_duration, but present at reference\_time.
                -  "REMOVED": indicates that the asset was present at the start of
                   compare\_duration, but not present at reference\_time.
                -  "ACTIVE": indicates that the asset was present at both the start and
                   the end of the time period defined by compare\_duration and
                   reference\_time.

                If compare\_duration is not specified, then the only possible
                state\_change is "UNUSED", which will be the state\_change set for all
                assets present at read\_time.

                If this field is set then ``state_change`` must be a specified field in
                ``group_by``.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.securitycenter_v1.types.Duration`
            read_time (Union[dict, ~google.cloud.securitycenter_v1.types.Timestamp]): Time used as a reference point when filtering assets. The filter is limited
                to assets existing at the supplied time and their values are those at that
                specific time. Absence of this field will default to the API's version of
                NOW.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.securitycenter_v1.types.Timestamp`
            page_size (int): The maximum number of resources contained in the
                underlying API response. If page streaming is performed per-
                resource, this parameter does not affect the return value. If page
                streaming is performed per-page, this determines the maximum number
                of resources in a page.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Returns:
            A :class:`~google.gax.PageIterator` instance. By default, this
            is an iterable of :class:`~google.cloud.securitycenter_v1.types.GroupResult` instances.
            This object can also be configured to iterate over the pages
            of the response through the `options` parameter.

        Args:
            parent (str): Name of the source to groupBy. Its format is
                "organizations/[organization\_id]/sources/[source\_id]". To groupBy
                across all sources provide a source\_id of ``-``. For example:
                organizations/123/sources/-
            group_by (str): Expression that defines what assets fields to use for grouping
                (including ``state_change``). The string value should follow SQL syntax:
                comma separated list of fields. For example: "parent,resource\_name".

                The following fields are supported:

                -  resource\_name
                -  category
                -  state
                -  parent

                The following fields are supported when compare\_duration is set:

                -  state\_change
            filter_ (str): Expression that defines the filter to apply across findings. The
                expression is a list of one or more restrictions combined via logical
                operators ``AND`` and ``OR``. Parentheses are supported, and ``OR`` has
                higher precedence than ``AND``.

                Restrictions have the form ``<field> <operator> <value>`` and may have a
                ``-`` character in front of them to indicate negation. Examples include:

                -  name
                -  source\_properties.a\_property
                -  security\_marks.marks.marka

                The supported operators are:

                -  ``=`` for all value types.
                -  ``>``, ``<``, ``>=``, ``<=`` for integer values.
                -  ``:``, meaning substring matching, for strings.

                The supported value types are:

                -  string literals in quotes.
                -  integer literals without quotes.
                -  boolean literals ``true`` and ``false`` without quotes.

                The following field and operator combinations are supported: name \|
                ``=`` parent \| '=', ':' resource\_name \| '=', ':' state \| '=', ':'
                category \| '=', ':' external\_uri \| '=', ':' event\_time \| ``>``,
                ``<``, ``>=``, ``<=`` security\_marks \| '=', ':' source\_properties \|
                '=', ':', ``>``, ``<``, ``>=``, ``<=``

                For example, ``source_properties.size = 100`` is a valid filter string.
            read_time (Union[dict, ~google.cloud.securitycenter_v1.types.Timestamp]): Time used as a reference point when filtering findings. The filter is
                limited to findings existing at the supplied time and their values are
                those at that specific time. Absence of this field will default to the
                API's version of NOW.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.securitycenter_v1.types.Timestamp`
            compare_duration (Union[dict, ~google.cloud.securitycenter_v1.types.Duration]): When compare\_duration is set, the GroupResult's "state\_change"
                attribute is updated to indicate whether the finding had its state
                changed, the finding's state remained unchanged, or if the finding was
                added during the compare\_duration period of time that precedes the
                read\_time. This is the time between (read\_time - compare\_duration)
                and read\_time.

                The state\_change value is derived based on the presence and state of
                the finding at the two points in time. Intermediate state changes
                between the two times don't affect the result. For example, the results
                aren't affected if the finding is made inactive and then active again.

                Possible "state\_change" values when compare\_duration is specified:

                -  "CHANGED": indicates that the finding was present at the start of
                   compare\_duration, but changed its state at read\_time.
                -  "UNCHANGED": indicates that the finding was present at the start of
                   compare\_duration and did not change state at read\_time.
                -  "ADDED": indicates that the finding was not present at the start of
                   compare\_duration, but was present at read\_time.

                If compare\_duration is not specified, then the only possible
                state\_change is "UNUSED", which will be the state\_change set for all
                findings present at read\_time.

                If this field is set then ``state_change`` must be a specified field in
                ``group_by``.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.securitycenter_v1.types.Duration`
            page_size (int): The maximum number of resources contained in the
                underlying API response. If page streaming is performed per-
                resource, this parameter does not affect the return value. If page
                streaming is performed per-page, this determines the maximum number
                of resources in a page.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Returns:
            A :class:`~google.gax.PageIterator` instance. By default, this
            is an iterable of :class:`~google.cloud.securitycenter_v1.types.GroupResult` instances.
            This object can also be configured to iterate over the pages
            of the response through the `options` parameter.

        Raises:

                    failed for any reason.

        Args:
            parent (str): Name of the organization assets should belong to. Its format is
                "organizations/[organization\_id]".
            filter_ (str): Expression that defines the filter to apply across assets. The
                expression is a list of zero or more restrictions combined via logical
                operators ``AND`` and ``OR``. Parentheses are supported, and ``OR`` has
                higher precedence than ``AND``.

                Restrictions have the form ``<field> <operator> <value>`` and may have a
                ``-`` character in front of them to indicate negation. The fields map to
                those defined in the Asset resource. Examples include:

                -  name
                -  security\_center\_properties.resource\_name
                -  resource\_properties.a\_property
                -  security\_marks.marks.marka

                The supported operators are:

                -  ``=`` for all value types.
                -  ``>``, ``<``, ``>=``, ``<=`` for integer values.
                -  ``:``, meaning substring matching, for strings.

                The supported value types are:

                -  string literals in quotes.
                -  integer literals without quotes.
                -  boolean literals ``true`` and ``false`` without quotes.

                The following are the allowed field and operator combinations: name \|
                ``=`` update\_time \| ``>``, ``<``, ``>=``, ``<=``
                iam\_policy.policy\_blob \| '=', ':' resource\_properties \| '=', ':',

                security\_center\_properties.resource\_project \| '=', ':'
                security\_center\_properties.resource\_owners \| '=', ':'

                For example, ``resource_properties.size = 100`` is a valid filter
                string.
            order_by (str): Expression that defines what fields and order to use for sorting. The
                string value should follow SQL syntax: comma separated list of fields.
                For example: "name,resource\_properties.a\_property". The default
                sorting order is ascending. To specify descending order for a field, a
                suffix " desc" should be appended to the field name. For example: "name
                desc,resource\_properties.a\_property". Redundant space characters in
                the syntax are insignificant. "name
                desc,resource\_properties.a\_property" and " name desc ,
                resource\_properties.a\_property " are equivalent.

                The following fields are supported: name update\_time
                resource\_properties security\_marks
                security\_center\_properties.resource\_name
                security\_center\_properties.resource\_parent

                security\_center\_properties.resource\_type
            read_time (Union[dict, ~google.cloud.securitycenter_v1.types.Timestamp]): Time used as a reference point when filtering assets. The filter is limited
                to assets existing at the supplied time and their values are those at that
                specific time. Absence of this field will default to the API's version of
                NOW.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.securitycenter_v1.types.Timestamp`
            compare_duration (Union[dict, ~google.cloud.securitycenter_v1.types.Duration]): When compare\_duration is set, the ListAssetsResult's "state\_change"
                attribute is updated to indicate whether the asset was added, removed,
                or remained present during the compare\_duration period of time that
                precedes the read\_time. This is the time between (read\_time -
                compare\_duration) and read\_time.

                The state\_change value is derived based on the presence of the asset at
                the two points in time. Intermediate state changes between the two times
                don't affect the result. For example, the results aren't affected if the
                asset is removed and re-created again.

                Possible "state\_change" values when compare\_duration is specified:

                -  "ADDED": indicates that the asset was not present at the start of
                   compare\_duration, but present at read\_time.
                -  "REMOVED": indicates that the asset was present at the start of
                   compare\_duration, but not present at read\_time.
                -  "ACTIVE": indicates that the asset was present at both the start and
                   the end of the time period defined by compare\_duration and
                   read\_time.

                If compare\_duration is not specified, then the only possible
                state\_change is "UNUSED", which will be the state\_change set for all
                assets present at read\_time.

            field_mask (Union[dict, ~google.cloud.securitycenter_v1.types.FieldMask]): Optional.

                A field mask to specify the ListAssetsResult fields to be listed in the
                response.
                An empty field mask will list all fields.

                message :class:`~google.cloud.securitycenter_v1.types.FieldMask`
            page_size (int): The maximum number of resources contained in the
                underlying API response. If page streaming is performed per-
                resource, this parameter does not affect the return value. If page
                streaming is performed per-page, this determines the maximum number
                of resources in a page.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata

        Lists an organization or source's findings.

        To list across all sources provide a ``-`` as the source id. Example:
        /v1/organizations/123/sources/-/findings

        Example:
            >>> from google.cloud import securitycenter_v1
            >>>
            >>> client = securitycenter_v1.SecurityCenterClient()

            ...         pass

        Args:
            parent (str): Name of the source the findings belong to. Its format is
                "organizations/[organization\_id]/sources/[source\_id]". To list across
                all sources provide a source\_id of ``-``. For example:
                organizations/123/sources/-
            filter_ (str): Expression that defines the filter to apply across findings. The
                expression is a list of one or more restrictions combined via logical
                operators ``AND`` and ``OR``. Parentheses are supported, and ``OR`` has
                higher precedence than ``AND``.

                Restrictions have the form ``<field> <operator> <value>`` and may have a
                ``-`` character in front of them to indicate negation. Examples include:

                -  name
                -  source\_properties.a\_property
                -  security\_marks.marks.marka

                The supported operators are:

                -  ``=`` for all value types.
                -  ``>``, ``<``, ``>=``, ``<=`` for integer values.
                -  ``:``, meaning substring matching, for strings.

                The supported value types are:

                -  string literals in quotes.
                -  integer literals without quotes.
                -  boolean literals ``true`` and ``false`` without quotes.

                The following field and operator combinations are supported: name \|
                ``=`` parent \| '=', ':' resource\_name \| '=', ':' state \| '=', ':'
                category \| '=', ':' external\_uri \| '=', ':' event\_time \| ``>``,
                ``<``, ``>=``, ``<=`` security\_marks \| '=', ':' source\_properties \|
                '=', ':', ``>``, ``<``, ``>=``, ``<=``

                For example, ``source_properties.size = 100`` is a valid filter string.
            order_by (str): Expression that defines what fields and order to use for sorting. The
                string value should follow SQL syntax: comma separated list of fields.
                For example: "name,resource\_properties.a\_property". The default
                sorting order is ascending. To specify descending order for a field, a
                suffix " desc" should be appended to the field name. For example: "name
                desc,source\_properties.a\_property". Redundant space characters in the
                syntax are insignificant. "name desc,source\_properties.a\_property" and
                " name desc , source\_properties.a\_property " are equivalent.

                The following fields are supported: name parent state category
                resource\_name event\_time source\_properties security\_marks
            read_time (Union[dict, ~google.cloud.securitycenter_v1.types.Timestamp]): Time used as a reference point when filtering findings. The filter is
                limited to findings existing at the supplied time and their values are
                those at that specific time. Absence of this field will default to the
                API's version of NOW.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.securitycenter_v1.types.Timestamp`
            compare_duration (Union[dict, ~google.cloud.securitycenter_v1.types.Duration]): When compare\_duration is set, the ListFindingsResult's "state\_change"
                attribute is updated to indicate whether the finding had its state
                changed, the finding's state remained unchanged, or if the finding was
                added in any state during the compare\_duration period of time that
                precedes the read\_time. This is the time between (read\_time -
                compare\_duration) and read\_time.

                The state\_change value is derived based on the presence and state of
                the finding at the two points in time. Intermediate state changes
                between the two times don't affect the result. For example, the results
                aren't affected if the finding is made inactive and then active again.

                Possible "state\_change" values when compare\_duration is specified:

                -  "CHANGED": indicates that the finding was present at the start of
                   compare\_duration, but changed its state at read\_time.
                -  "UNCHANGED": indicates that the finding was present at the start of
                   compare\_duration and did not change state at read\_time.
                -  "ADDED": indicates that the finding was not present at the start of
                   compare\_duration, but was present at read\_time.

                If compare\_duration is not specified, then the only possible
                state\_change is "UNUSED", which will be the state\_change set for all
                findings present at read\_time.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.securitycenter_v1.types.Duration`
            field_mask (Union[dict, ~google.cloud.securitycenter_v1.types.FieldMask]): Optional.

                A field mask to specify the Finding fields to be listed in the response.
                An empty field mask will list all fields.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.securitycenter_v1.types.FieldMask`
            page_size (int): The maximum number of resources contained in the
                underlying API response. If page streaming is performed per-
                resource, this parameter does not affect the return value. If page
                streaming is performed per-page, this determines the maximum number
                of resources in a page.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Returns:
            A :class:`~google.gax.PageIterator` instance. By default, this
            is an iterable of :class:`~google.cloud.securitycenter_v1.types.ListFindingsResult` instances.
            This object can also be configured to iterate over the pages
            of the response through the `options` parameter.

        Raises:

                    failed for any reason.
