    <code class="details" id="aggregatedList">aggregatedList(project, filter=None, includeAllScopes=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None)</code>
  <pre>Retrieves the list of all UrlMap resources, regional and global, available to the specified project.

Args:
  project: string, Name of the project scoping this request. (required)
  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 `=`, `!=`, `&gt;`, or `&lt;`.

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 = &quot;Intel Skylake&quot;) ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = &quot;Intel Skylake&quot;) OR (cpuPlatform = &quot;Intel Broadwell&quot;) AND (scheduling.automaticRestart = true) ```
  includeAllScopes: boolean, Indicates whether every visible scope for each scope type (zone, region, global) should be included in the response. For new resource types added after this field, the flag has no effect as new resource types will always include every visible scope for each scope type in response. For resource types which predate this field, if this flag is omitted or false, only scopes of the scope types where the resource type is expected to be found will be included.
  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`)
  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=&quot;creationTimestamp desc&quot;`. 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.
  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.
  returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false and the logic is the same as today.

Returns:
  An object of the form:

  <pre>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 &#x27;execute()&#x27; on to request the next
  page. Returns None if there are no more items in the collection.

  <pre>Close httplib2 connections.</pre>
</div>

<div class="method">
    <code class="details" id="delete">delete(project, urlMap, requestId=None)</code>
  <pre>Deletes the specified UrlMap resource.

Args:
  project: string, Project ID for this request. (required)
  urlMap: string, Name of the UrlMap 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:
  An object of the form:

}

  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).

<div class="method">
    <code class="details" id="list">list(project, filter=None, maxResults=None, orderBy=None, pageToken=None, returnPartialSuccess=None)</code>
  <pre>Retrieves the list of UrlMap resources available to the specified project.

Args:
  project: string, Project ID for this request. (required)
  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 `=`, `!=`, `&gt;`, or `&lt;`.

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 = &quot;Intel Skylake&quot;) ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = &quot;Intel Skylake&quot;) OR (cpuPlatform = &quot;Intel Broadwell&quot;) AND (scheduling.automaticRestart = true) ```
  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`)
  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=&quot;creationTimestamp desc&quot;`. 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.
  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.
  returnPartialSuccess: boolean, Opt-in for partial success behavior which provides partial results in case of failure. The default value is false and the logic is the same as today.

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).

  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:
