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

java.lang.Object
  extended by org.apache.http.nio.util.ExpandableBuffer
      extended by org.apache.cxf.transport.http.asyncclient.SharedOutputBuffer
All Implemented Interfaces:
org.apache.http.nio.util.BufferInfo
@ThreadSafe
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).

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.
