     *           The address of the API remote host. May optionally include the port, formatted
     *           as "<uri>:<port>". Default 'compute.googleapis.com:443'.
     *     @type string|array|FetchAuthTokenInterface|CredentialsWrapper $credentials
     *           The credentials to be used by the client to authorize API calls. This option
     *           accepts either a path to a credentials file, or a decoded credentials file as a

     *           Determines whether or not retries defined by the client configuration should be

     *           a path to a JSON file, or a PHP array containing the decoded JSON data. By
     *           default this settings points to the default client config file, which is
     *           provided in the resources folder.

     *           The transport used for executing network requests. At the moment, supports only

     *     @type string $filter
     *           A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The 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`. The `:` operator can be used with string fields to match substrings. For non-string fields it is equivalent to the `=` operator. The `:*` comparison can be used to test whether a key has been defined. For example, to find all objects with `owner` label use: ``` labels.owner:* ``` 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) ``` If you want to use a regular expression, use the `eq` (equal) or `ne` (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: `fieldname eq unquoted literal` `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"` `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use `name ne .*instance`.
     *     @type int $maxResults
     *           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`)
     *     @type string $orderBy
     *           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.
     *     @type string $pageToken
     *           A page token is used to specify a page of values to be returned.
     *           If no page token is specified (the default), the first page
     *           of values will be returned. Any page token used here must have
     *           been generated by a previous call to the API.
