/**
 * Service Description: Service for managing [Participants][google.cloud.dialogflow.v2.Participant].
 *
 * 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:
 *
 * ```
 * $participantsClient = new ParticipantsClient();
 * try {
 *     $formattedParticipant = $participantsClient->participantName('[PROJECT]', '[CONVERSATION]', '[PARTICIPANT]');
 *     $response = $participantsClient->analyzeContent($formattedParticipant);
 * } finally {
 *     $participantsClient->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.
