public abstract class AbstractExecutorChannel
extends AbstractSubscribableChannel
implements ExecutorChannelInterceptorAware

The AbstractSubscribableChannel base implementation for those inheritors which logic may be based on the Executor.

Utilizes common operations for the AbstractDispatcher.

Implements the ExecutorChannelInterceptors logic when the message handling is handed to the Executor.execute(Runnable).

Since:

4.2
