/**
 * Service Description: Manages the resources required for ACME [external account
 * binding](https://tools.ietf.org/html/rfc8555#section-7.3.4) for
 * the public certificate authority service.
 *
 * 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:
 *
 * ```
 * $publicCertificateAuthorityServiceClient = new PublicCertificateAuthorityServiceClient();
 * try {
 *     $formattedParent = $publicCertificateAuthorityServiceClient->locationName('[PROJECT]', '[LOCATION]');
 *     $externalAccountKey = new ExternalAccountKey();
 *     $response = $publicCertificateAuthorityServiceClient->createExternalAccountKey($formattedParent, $externalAccountKey);
 * } finally {
 *     $publicCertificateAuthorityServiceClient->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.
