## Instance Methods

Creates a message and sends a notification to the Cloud Pub/Sub topic. If

Deletes an HL7v2 message.

Gets an HL7v2 message.

Ingests a new HL7v2 message from the hospital and sends a notification to

### Method Details

`create(parent, body, x__xgafv=None)`

    Creates a message and sends a notification to the Cloud Pub/Sub topic. If
    configured, the MLLP adapter listens to messages created by this method and
    sends those back to the hospital. A successful response indicates the
    message has been persisted to storage and a Cloud Pub/Sub notification has
    been sent. Sending to the hospital by the MLLP adapter happens
    asynchronously.

`list(parent, orderBy=None, pageSize=None, pageToken=None, x__xgafv=None, filter=None)`

    Lists all the messages in the given HL7v2 store with support for filtering.

    Args:
      parent: string, Name of the HL7v2 store to retrieve messages from. (required)
      orderBy: string, Orders messages returned by the specified order_by clause.
    Syntax: https://cloud.google.com/apis/design/design_patterns#sorting_order

    Fields available for ordering are:

    *  `send_time`
      pageSize: integer, Limit on the number of messages to return in a single response.
    If zero the default page size of 100 is used.
      pageToken: string, The next_page_token value returned from the previous List request, if any.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
      filter: string, Restricts messages returned to those matching a filter. Syntax:
    https://cloud.google.com/appengine/docs/standard/python/search/query_strings

    Fields/functions available for filtering are:

    *  `message_type`, from the MSH-9 segment; for example
    `NOT message_type = "ADT"`
    *  `send_date` or `sendDate`, the YYYY-MM-DD date the message was sent in
    the dataset's time_zone, from the MSH-7 segment; for example
    `send_date < "2017-01-02"`
    *  `send_time`, the timestamp of when the message was sent, using the
    RFC3339 time format for comparisons, from the MSH-7 segment; for example
    `send_time < "2017-01-02T00:00:00-05:00"`
    *  `send_facility`, the care center that the message came from, from the
    MSH-4 segment; for example `send_facility = "ABC"`
    *  `HL7RegExp(expr)`, which does regular expression matching of `expr`
    against the message payload using re2 (http://code.google.com/p/re2/)
    syntax; for example `HL7RegExp("^.*\|.*\|EMERG")`
    *  `PatientId(value, type)`, which matches if the message lists a patient
    having an ID of the given value and type in the PID-2, PID-3, or PID-4
    segments; for example `PatientId("123456", "MRN")`
    *  `labels.x`, a string value of the label with key `x` as set using the
    Message.labels
    map, for example `labels."priority"="high"`. The operator `:*` can be used
    to assert the existence of a label, for example `labels."priority":*`.

    Limitations on conjunctions:

    *  Negation on the patient ID function or the labels field is not
    supported, for example these queries are invalid:
    `NOT PatientId("123456", "MRN")`, `NOT labels."tag1":*`,
    `NOT labels."tag2"="val2"`.
    *  Conjunction of multiple patient ID functions is not supported, for
    example this query is invalid:
    `PatientId("123456", "MRN") AND PatientId("456789", "MRN")`.
    *  Conjunction of multiple labels fields is also not supported, for
    example this query is invalid: `labels."tag1":* AND labels."tag2"="val2"`.
    *  Conjunction of one patient ID function, one labels field and conditions
    on other fields is supported, for example this query is valid:
    `PatientId("123456", "MRN") AND labels."tag1":* AND message_type = "ADT"`.

    The HasLabel(x) and Label(x) syntax from previous API versions are
    deprecated; replaced by the `labels.x` syntax.

    Returns:
      An object of the form:

        { # Lists the messages in the specified HL7v2 store.
        "nextPageToken": "A String", # Token to retrieve the next page of results or empty if there are no more
            # results in the list.
        "messages": [ # The returned message names. Won't be more values than the value of
            # page_size in the request.
          "A String",
        ],
      }

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:
      previous_request: The request for the previous page. (required)
      previous_response: The response from the request for the previous page. (required)

    Returns:
      A request object that you can call 'execute()' on to request the next
      page. Returns None if there are no more items in the collection.

`patch(name, body, updateMask=None, x__xgafv=None)`

    Update the message.

    Args:
