Class PipeliningClientExchangeHandlerImpl<T>

java.lang.Object

org.apache.http.impl.nio.client.AbstractClientExchangeHandler

org.apache.http.impl.nio.client.PipeliningClientExchangeHandlerImpl<T>

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, org.apache.http.concurrent.Cancellable, org.apache.http.nio.protocol.HttpAsyncClientExchangeHandler

@Pipelined
class PipeliningClientExchangeHandlerImpl<T>
extends AbstractClientExchangeHandler

HttpAsyncClientExchangeHandler implementation that supports HTTP message pipelining.

Instances of this class are expected to be accessed by one thread at a time only. The AbstractClientExchangeHandler.cancel() method can be called concurrently by multiple threads.
