# Compute Engine API . globalForwardingRules

## Instance Methods

Deletes the specified GlobalForwardingRule resource.

Returns the specified GlobalForwardingRule resource. Gets a list of available forwarding rules by making a list() request.

Creates a GlobalForwardingRule resource in the specified project using the data included in the request.

Retrieves a list of GlobalForwardingRule resources available to the specified project.

Retrieves the next page of results.

Changes target URL for the GlobalForwardingRule resource. The new target should be of the same type as the old target.

### Method Details

`delete(project, forwardingRule, requestId=None)`

    Deletes the specified GlobalForwardingRule resource.

    Args:
      project: string, Project ID for this request. (required)
      forwardingRule: string, Name of the ForwardingRule resource to delete. (required)
      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.

    For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

    The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

    Returns:

      }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.

    For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

    The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

`list(project, orderBy=None, maxResults=None, pageToken=None, filter=None)`

    Retrieves a list of GlobalForwardingRule resources available to the specified project.

    Args:
      project: string, Project ID for this request. (required)
      orderBy: string, Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.

    You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first.

    Currently, only sorting by name or creationTimestamp desc is supported.
      maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500)
      pageToken: string, Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
      filter: string, A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either =, !=, >, or <.

    For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.

    You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels.

    To filter on multiple expressions, provide each separate expression within parentheses. For example, (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake"). By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example, (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true).

    Returns:
      An object of the form:

`list_next(previous_request, previous_response)`

    Retrieves the next page of results.

    Args:

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

`setTarget(project, forwardingRule, body, requestId=None)`

      forwardingRule: string, Name of the ForwardingRule resource in which target is to be set. (required)
      body: object, The request body. (required)
        The object takes the form of:

    {
        "target": "A String",
      }

      requestId: string, An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.

    For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

    The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

For example, for warnings where there are no results in a list request for a particular zone, this key might be scope and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
