/**
 * Service Description: An intent represents a mapping between input from a user and an action to
 * be taken by your application. When you pass user input to the
 * [DetectIntent][google.cloud.dialogflow.v2.Sessions.DetectIntent] (or
 * [StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent]) method, the
 * Dialogflow API analyzes the input and searches
 * for a matching intent. If no match is found, the Dialogflow API returns a
 * fallback intent (`is_fallback` = true).
 *
 * You can provide additional information for the Dialogflow API to use to
 * match user input to an intent by adding the following to your intent.
 *
 * *   **Contexts** - provide additional context for intent analysis. For
 *     example, if an intent is related to an object in your application that
 *     plays music, you can provide a context to determine when to match the
 *     intent if the user input is "turn it off". You can include a context
 *     that matches the intent when there is previous user input of
 *     "play music", and not when there is previous user input of
 *     "turn on the light".
 *
 * *   **Events** - allow for matching an intent by using an event name
 *     instead of user input. Your application can provide an event name and
 *     related parameters to the Dialogflow API to match an intent. For
 *     example, when your application starts, you can send a welcome event
 *     with a user name parameter to the Dialogflow API to match an intent with
 *     a personalized welcome message for the user.
 *
 * *   **Training phrases** - provide examples of user input to train the
 *     Dialogflow API agent to better match intents.
 *
 * For more information about intents, see the
 * [Dialogflow
 * documentation](https://cloud.google.com/dialogflow/docs/intents-overview).
 *
 * 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:
 *
 * ```
 * $intentsClient = new IntentsClient();
 * try {
 *     $formattedParent = $intentsClient->projectAgentName('[PROJECT]');
 *     // Iterate over pages of elements
 *     $pagedResponse = $intentsClient->listIntents($formattedParent);
 *     foreach ($pagedResponse->iteratePages() as $page) {
 *         foreach ($page as $element) {
 *             // doSomethingWith($element);
 *         }
 *     }
 *
 *
 *     // Alternatively:
 *
 *     // Iterate through all elements
 *     $pagedResponse = $intentsClient->listIntents($formattedParent);
 *     foreach ($pagedResponse->iterateAllElements() as $element) {
 *         // doSomethingWith($element);
 *     }
 * } finally {
 *     $intentsClient->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.
