/**
 * Service Description: A service that handles resume parsing.
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods. Sample code to get started:
 *
 * ```
 * $resumeServiceClient = new ResumeServiceClient();
 * try {
 *     $formattedParent = $resumeServiceClient->projectName('[PROJECT]');
 *     $resume = '';
 *     $response = $resumeServiceClient->parseResume($formattedParent, $resume);
 * } finally {
 *     $resumeServiceClient->close();
 * }
 * ```
 *
 * Many parameters require resource names to be formatted in a particular way. To assist
 * with these names, this class includes a format method for each type of name, and additionally
 * a parseName method to extract the individual identifiers contained within formatted names
 * that are returned by the API.
 *

     * * emailAddress
     * * phoneNumbers

     *
     * This API does not save the resume or profile. To create a profile from this
     * resume, clients need to call the CreateProfile method again with the
     * profile returned.
     *
     * This API supports the following list of formats:
     *
     * * PDF
     * * TXT
     * * DOC
     * * RTF
     * * DOCX
     *
     * An error is thrown if the input format is not supported.

     *     $formattedParent = $resumeServiceClient->projectName('[PROJECT]');
     *     $resume = '';

     * "projects/api-test-project".
     * @param string $resume Required.

     *          parsing quality and performance.
     *
