Class ResponseBodyDeferringAsyncHandler

java.lang.Object

org.mule.service.http.impl.service.client.async.ResponseBodyDeferringAsyncHandler

All Implemented Interfaces:

com.ning.http.client.AsyncHandler<com.ning.http.client.Response>

public class ResponseBodyDeferringAsyncHandler
extends Object
implements com.ning.http.client.AsyncHandler<com.ning.http.client.Response>

Non blocking async handler which uses a PipedOutputStream to populate the HTTP response as it arrives, propagating an PipedInputStream as soon as the response headers are parsed.

Because of the internal buffer used to hold the arriving chunks, the response MUST be eventually read or the worker threads will block waiting to allocate them. Likewise, read/write speed differences could cause issues. The buffer size can be customized for these reason.

To avoid deadlocks, a hand off to another thread MUST be performed before consuming the response.
