Product Reference

Service Description: The Reservations API.

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:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (ReservationsClient reservationsClient = ReservationsClient.create()) {
   String project = "project-309310695";
   String zone = "zone3744684";
   String reservation = "reservation-1563081780";
   Reservation response = reservationsClient.get(project, zone, reservation);
 }
 

Note: close() needs to be called on the ReservationsClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods

Method	Description	Method Variants
AggregatedList	Retrieves an aggregated list of reservations.	Request object method variants only take one parameter, a request object, which must be constructed before the call. aggregatedList(AggregatedListReservationsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. aggregatedList(String project) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. aggregatedListPagedCallable() aggregatedListCallable()
Delete	Deletes the specified reservation.	Request object method variants only take one parameter, a request object, which must be constructed before the call. deleteAsync(DeleteReservationRequest request) Methods that return long-running operations have "Async" method variants that return OperationFuture, which is used to track polling of the service. deleteAsync(String project, String zone, String reservation) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. deleteOperationCallable() deleteCallable()
Get	Retrieves information about the specified reservation.

See the individual methods for example code.

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 parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of ReservationsSettings to create(). For example:

To customize credentials:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ReservationsSettings reservationsSettings =
     ReservationsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ReservationsClient reservationsClient = ReservationsClient.create(reservationsSettings);
 

To customize the endpoint:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ReservationsSettings reservationsSettings =
     ReservationsSettings.newBuilder().setEndpoint(myEndpoint).build();
 ReservationsClient reservationsClient = ReservationsClient.create(reservationsSettings);
