Package com.google.gwt.user.client.rpc

Classes used in client-side implementation of remote procedure calls. Most applications will be interested in AsyncCallback, InvocationException, RemoteService, and ServiceDefTarget. The other classes in this package are used primarily in implementing RPC proxies.

Interface Summary

Interface	Description
AsyncCallback<T>	The primary interface a caller must implement to receive a response from a remote procedure call.
HasRpcToken	An interface implemented by client-side RPC proxy objects.
IsSerializable	Marker interface indicating that a type is intended to be used with a RemoteService.
RemoteService	Marker interface that RPC interfaces should extend.
RpcToken	An interface for RPC token implementation objects included with each RPC call.
RpcTokenExceptionHandler	Handles an exception produced while processing RpcToken.
SerializationStreamFactory	An interface for creating SerializationStreamReaders and SerializationStreamWriters.
SerializationStreamReader	An interface for reading values from a stream.
SerializationStreamWriter	An interface for writing values into a stream.
ServiceDefTarget	An interface implemented by client-side RPC proxy objects.
XsrfProtectedService	XSRF protected equivalent of RemoteService.
XsrfProtectedServiceAsync	Async peer of XsrfProtectedService.
XsrfTokenService	XSRF token generation RPC service.
XsrfTokenServiceAsync	Async peer of XsrfTokenService.

Class Summary

Class	Description
CustomFieldSerializer<T>	An interface that may be implemented by class-based custom field serializers which will reduce the amount of server-side reflection during serialization, hence improving their serialization performance.
RpcRequestBuilder	This class encapsulates the logic necessary to configure a RequestBuilder for use with an RPC proxy object.
XsrfToken	XSRF token.

Exception Summary

Exception	Description
IncompatibleRemoteServiceException	Exception that will be passed to the AsyncCallback.onFailure(Throwable) method when an incompatibility is detected between a RemoteService client and its corresponding RemoteService server.
InvocationException	Occurs when a service invocation did not complete cleanly.
RpcTokenException	Exception that will be passed to the RpcTokenExceptionHandler.onRpcTokenException(RpcTokenException) method when RPC token processing resulted in an error.
SerializableException	Deprecated. As of GWT 1.5, Exception implements Serializable and can be used in place of this class
SerializationException	Base exception type for errors relating to the serialization stream.
SerializedTypeViolationException	Exception that will be passed to the AsyncCallback.onFailure(Throwable) method when the value of an argument to a method in an RPC message is of the incorrect type.
ServiceDefTarget.NoServiceEntryPointSpecifiedException	This exception is thrown when a service is invoked without ServiceDefTarget.setServiceEntryPoint(String) having been called.
StatusCodeException	Indicates that an RPC response was returned with an invalid HTTP status code.

Annotation Types Summary

Annotation Type	Description
GwtTransient	This annotation means the same thing as the transient keyword, but it is ignored by all serialization systems other than GWT's.
RemoteServiceRelativePath	Associates a RemoteService with a relative path.
RpcToken.RpcTokenImplementation	RemoteService interfaces specifying RpcToken implementation using this annotation will only have serializers for the specific class generated, as opposed to generating serializers for all RpcToken implementations.
