See: Description
| 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 andSerializationStreamWriters. | 
| 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 | 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 | Description | 
|---|---|
| IncompatibleRemoteServiceException | Exception that will be passed to the
  AsyncCallback.onFailure(Throwable)method when an incompatibility is
 detected between aRemoteServiceclient and its correspondingRemoteServiceserver. | 
| 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,  ExceptionimplementsSerializableand 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 Type | Description | 
|---|---|
| GwtTransient | This annotation means the same thing as the  transientkeyword,
 but it is ignored by all serialization systems other than GWT's. | 
| RemoteServiceRelativePath | Associates a  RemoteServicewith a relative path. | 
| RpcToken.RpcTokenImplementation | RemoteServiceinterfaces specifyingRpcTokenimplementation
 using this annotation will only have serializers for the specific class
 generated, as opposed to generating serializers for allRpcTokenimplementations. |
