get(topic, x__xgafv=None)

Gets the configuration of a topic.

getIamPolicy(resource, x__xgafv=None)

Gets the access control policy for a resource. Is empty if the policy or the resource does not exist.

Lists matching topics.

list_next(previous_request, previous_response)

Retrieves the next page of results.

publish(topic, body, x__xgafv=None)

    { # # Overview The `Policy` defines an access control policy language. It is used to define policies that are attached to resources like files, folders, VMs, etc. # Policy structure A `Policy` consists of a list of bindings. A `Binding` binds a set of members to a role, where the members include user accounts, user groups, user domains, and service accounts. A 'role' is a named set of permissions, defined by IAM. The definition of a role is outside the policy. A permission check first determines the roles that include the specified permission, and then determines if the principal specified is a member of a binding to at least one of these roles. The membership check is recursive when a group is bound to a role. Policy examples: ``` { "bindings": [ { "role": "roles/owner", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:frontend@example.iam.gserviceaccounts.com"] }, { "role": "roles/viewer", "members": ["user:sean@example.com"] } ] } ```
    "bindings": [ # It is an error to specify multiple bindings for the same role. It is an error to specify a binding with no members.
      { # Associates members with roles. See below for allowed formats of members.
        "role": "A String", # The name of the role to which the members should be bound. Examples: "roles/viewer", "roles/editor", "roles/owner". Required
        "members": [ # Format of member entries: 1. allUsers Matches any requesting principal (users, service accounts or anonymous). 2. allAuthenticatedUsers Matches any requesting authenticated principal (users or service accounts). 3. user:{emailid} A google user account using an email address. For example alice@gmail.com, joe@example.com 4. serviceAccount:{emailid} An service account email. 5. group:{emailid} A google group with an email address. For example auth-ti-cloud@google.com 6. domain:{domain} A Google Apps domain name. For example google.com, example.com
          "A String",
        ],
      },
    ],
    "version": 42, # The policy language version. The version of the policy is represented by the etag. The default version is 0.
    "etag": "A String", # Can be used to perform a read-modify-write.
  }
list(project, pageSize=None, pageToken=None, x__xgafv=None)
Lists matching topics.

Args:
  project: string, The name of the cloud project that topics belong to. (required)
  pageSize: integer, Maximum number of topics to return.
  pageToken: string, The value returned by the last ListTopicsResponse; indicates that this is a continuation of a prior ListTopics call, and that the system should return the next page of data.
  x__xgafv: string, V1 error format.

Returns:
  An object of the form:

    { # Response for the ListTopics method.
    "nextPageToken": "A String", # If not empty, indicates that there may be more topics that match the request; this value should be passed in a new ListTopicsRequest.
    "topics": [ # The resulting topics.
      { # A topic resource.
        "name": "A String", # The name of the topic. It must have the format `"projects/{project}/topics/{topic}"`. `{topic}` must start with a letter, and contain only letters (`[A-Za-z]`), numbers (`[0-9]`), dashes (`-`), underscores (`_`), periods (`.`), tildes (`~`), plus (`+`) or percent signs (`%`). It must be between 3 and 255 characters in length, and it must not start with `"goog"`.

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.
    
publish(topic, body, x__xgafv=None)
Adds one or more messages to the topic. Returns NOT_FOUND if the topic does not exist. The message payload must not be empty; it must contain either a non-empty data field, or at least one attribute.

    ],
  }
setIamPolicy(resource, body, x__xgafv=None)
