Class QpidByteBufferOutputStream

java.lang.Object

java.io.OutputStream

org.apache.qpid.bytebuffer.QpidByteBufferOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class QpidByteBufferOutputStream
extends OutputStream

OutputStream implementation that yields a list QpidByteBuffers that contain a copy of the incoming bytes. Use fetchAccumulatedBuffers to get the buffers. Caller has responsibility to dispose the buffers after use. It will be normally be desirable to front this stream with java.io.BufferedOutputStream to minimise the number of write and thus the number of buffers created. Not thread safe.
