Interface Summary

Interface	Description
ChannelInterceptor	Interface for interceptors that are able to view and/or modify the Messages being sent-to and/or received-from a MessageChannel.
ExecutorChannelInterceptor	An extension of ChannelInterceptor with callbacks to intercept the asynchronous sending of a Message to a specific subscriber through an Executor.
HeaderMapper<T>	Generic strategy interface for mapping MessageHeaders to and from other types of objects.
InterceptableChannel	A MessageChannel that maintains a list ChannelInterceptors and allows interception of message sending.
MessageHandlingRunnable	Extension of the Runnable interface with methods to obtain the MessageHandler and Message to be handled.
MessageHeaderInitializer	Callback interface for initializing a MessageHeaderAccessor.

Class Summary

Class	Description
AbstractHeaderMapper<T>	A base HeaderMapper implementation.
AbstractMessageChannel	Abstract base class for MessageChannel implementations.
AbstractSubscribableChannel	Abstract base class for SubscribableChannel implementations.
ChannelInterceptorAdapter	Deprecated as of 5.0.7 ChannelInterceptor has default methods (made possible by a Java 8 baseline) and can be implemented directly without the need for this no-op adapter
ErrorMessage	A GenericMessage with a Throwable payload.
ExecutorSubscribableChannel	A SubscribableChannel that sends messages to each of its subscribers.
GenericMessage<T>	An implementation of Message with a generic payload.
IdTimestampMessageHeaderInitializer	A MessageHeaderInitializer to customize the strategy for ID and TIMESTAMP message header generation.
ImmutableMessageChannelInterceptor	A simpler interceptor that calls MessageHeaderAccessor.setImmutable() on the headers of messages passed through the preSend method.
MessageBuilder<T>	A builder for creating a GenericMessage (or ErrorMessage if the payload is of type Throwable).
MessageHeaderAccessor	A base for classes providing strongly typed getters and setters as well as behavior around specific categories of headers (e.g.
NativeMessageHeaderAccessor	An extension of MessageHeaderAccessor that also stores and provides read/write access to message headers from an external source -- e.g.
