All Implemented Interfaces:

public final class PipedExceptionInputStream
extends PipedInputStream

Functionally identical to PipedInputStream, except that when an exception is caught in the producer thread (the thread that writes data to associated PipedOutputStream) and it is registered in the registry then all read() methods will fail with the registered exception. For further details please see the documentation of ExceptionRegistry.
