## Instance Methods

Returns the operations Resource.

Close httplib2 connections.

Create an OS policy assignment. This method also creates the first revision of the OS policy assignment. This method returns a long running operation (LRO) that contains the rollout details. The rollout can be cancelled by cancelling the LRO. For more information, see [Method: projects.locations.osPolicyAssignments.operations.cancel](https://cloud.google.com/compute/docs/osconfig/rest/v1/projects.locations.osPolicyAssignments.operations/cancel).

Delete the OS policy assignment. This method creates a new revision of the OS policy assignment. This method returns a long running operation (LRO) that contains the rollout details. The rollout can be cancelled by cancelling the LRO. If the LRO completes and is not cancelled, all revisions associated with the OS policy assignment are deleted. For more information, see [Method: projects.locations.osPolicyAssignments.operations.cancel](https://cloud.google.com/compute/docs/osconfig/rest/v1/projects.locations.osPolicyAssignments.operations/cancel).

Retrieve an existing OS policy assignment. This method always returns the latest revision. In order to retrieve a previous revision of the assignment, also provide the revision ID in the `name` parameter.

List the OS policy assignments under the parent resource. For each OS policy assignment, the latest revision is returned.

List the OS policy assignment revisions for a given OS policy assignment.

Retrieves the next page of results.

Update an existing OS policy assignment. This method creates a new revision of the OS policy assignment. This method returns a long running operation (LRO) that contains the rollout details. The rollout can be cancelled by cancelling the LRO. For more information, see [Method: projects.locations.osPolicyAssignments.operations.cancel](https://cloud.google.com/compute/docs/osconfig/rest/v1/projects.locations.osPolicyAssignments.operations/cancel).

The `validate` stage can signal that the `ExecResource` is already in the desired state by returning an exit code of `100`. If the `ExecResource` is not in the desired state, it should return an exit code of `101`. Any other exit code returned by this stage is considered an error.

If the `ExecResource` is already in the desired state, the `enforce` stage will not be run. Similar to `validate` stage, the `enforce` stage should return an exit code of `100` to indicate that the resource in now in its desired state. Any other exit code is considered an error. NOTE: An exit code of `100` was chosen over `0` (and `101` vs `1`) to have an explicit indicator of `in desired state`, `not in desired state` and errors.

The `ExecResource` has 2 stages: `validate` and `enforce` and both stages accept a script as an argument to execute.

The `validate` stage can signal that the `ExecResource` is already in the desired state by returning an exit code of `100`. If the `ExecResource` is not in the desired state, it should return an exit code of `101`. Any other exit code returned by this stage is considered an error.

If the `ExecResource` is already in the desired state, the `enforce` stage will not be run. Similar to `validate` stage, the `enforce` stage should return an exit code of `100` to indicate that the resource in now in its desired state. Any other exit code is considered an error. NOTE: An exit code of `100` was chosen over `0` (and `101` vs `1`) to have an explicit indicator of `in desired state`, `not in desired state` and errors.
