# Cloud Resource Manager API . liens

## Instance Methods

Close httplib2 connections.

Create a Lien which applies to the resource denoted by the `parent` field. Callers of this method will require permission on the `parent` resource. For example, applying to `projects/1234` requires permission `resourcemanager.projects.updateLiens`. NOTE: Some resources may limit the number of Liens which may be applied.

Delete a Lien by `name`. Callers of this method will require permission on the `parent` resource. For example, a Lien with a `parent` of `projects/1234` requires permission `resourcemanager.projects.updateLiens`.

Retrieve a Lien by `name`. Callers of this method will require permission on the `parent` resource. For example, a Lien with a `parent` of `projects/1234` requires permission `resourcemanager.projects.get`

List all Liens applied to the `parent` resource. Callers of this method will require permission on the `parent` resource. For example, a Lien with a `parent` of `projects/1234` requires permission `resourcemanager.projects.get`.

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

    Create a Lien which applies to the resource denoted by the `parent` field. Callers of this method will require permission on the `parent` resource. For example, applying to `projects/1234` requires permission `resourcemanager.projects.updateLiens`. NOTE: Some resources may limit the number of Liens which may be applied.

    Args:
      body: object, The request body.
        The object takes the form of:

    { # A Lien represents an encumbrance on the actions that can be performed on a resource.
      "createTime": "A String", # The creation time of this Lien.
      "name": "A String", # A system-generated unique identifier for this Lien. Example: `liens/1234abcd`
      "origin": "A String", # A stable, user-visible/meaningful string identifying the origin of the Lien, intended to be inspected programmatically. Maximum length of 200 characters. Example: 'compute.googleapis.com'
      "parent": "A String", # A reference to the resource this Lien is attached to. The server will validate the parent against those for which Liens are supported. Example: `projects/1234`
      "reason": "A String", # Concise user-visible strings indicating why an action cannot be performed on a resource. Maximum length of 200 characters. Example: 'Holds production API key'
      "restrictions": [ # The types of operations which should be blocked as a result of this Lien. Each value should correspond to an IAM permission. The server will validate the permissions against those for which Liens are supported. An empty list is meaningless and will be rejected. Example: ['resourcemanager.projects.delete']
        "A String",
      ],
    }

      x__xgafv: string, V1 error format.

        { # A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); }
    }

`get(name, x__xgafv=None)`

    Retrieve a Lien by `name`. Callers of this method will require permission on the `parent` resource. For example, a Lien with a `parent` of `projects/1234` requires permission `resourcemanager.projects.get`
