Class SharedInputBuffer

java.lang.Object

org.apache.http.nio.util.ExpandableBuffer

org.apache.cxf.transport.http.asyncclient.SharedInputBuffer

All Implemented Interfaces:

org.apache.http.io.BufferInfo, org.apache.http.nio.util.BufferInfo

public class SharedInputBuffer
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 expect to transfer data from ContentDecoder to the buffer by calling #consumeContent(ContentDecoder).

The worker thread is expected to read the data from the buffer by calling read() or read(byte[], int, int) methods.

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