public class ReadableByteChannelWithConditionalBound<T extends ReadableByteChannel>
extends ReadableByteChannelDecoratorBase<T>

Readable byte channel wrapper that before every read checks for an end-of-file (eof) condition. Once true, any subsequent read immediatly returns -1 (eof). Used to prevent reading across hadoop split boundaries
