All Implemented Interfaces:

Closeable, Channel, ReadableByteChannel, BlockableChannel, ReadableSelectionChannel, SelectionChannel

public class ReadableTraceChannel
extends TraceChannel<ReadableSelectionChannel>
implements ReadableSelectionChannel

Trace byte channel that sends a copy of all data on the trace output stream. It is important to implement SelectionChannel as some framework classes rely on this down the processing chain.
