Class SharedOutputBuffer

java.lang.Object

org.apache.http.nio.util.ExpandableBuffer

org.apache.cxf.transport.http.asyncclient.SharedOutputBuffer

All Implemented Interfaces:

org.apache.http.nio.util.BufferInfo

public class SharedOutputBuffer
extends org.apache.http.nio.util.ExpandableBuffer

Content buffer that can be shared by multiple threads, usually the I/O dispatch of an I/O reactor and a worker thread.

The I/O dispatch thread is expected to transfer data from the buffer to ContentEncoder by calling produceContent(ContentEncoder, IOControl).

The worker thread is expected to write data to the buffer by calling write(int), write(byte[], int, int) or writeCompleted()

In case of an abnormal situation or when no longer needed the buffer must be shut down using shutdown() method.
