Method Detail

onDataAvailable

public void onDataAvailable()
                     throws IOException

Specified by:

onDataAvailable in interface ReadListener

Throws:

IOException

onAllDataRead

public void onAllDataRead()
                   throws IOException

Specified by:

onAllDataRead in interface ReadListener

Throws:

IOException

onError

public void onError(Throwable t)

Specified by:

onError in interface ReadListener

process

protected IteratingCallback.Action process()
                                    throws Exception

Description copied from class: IteratingCallback

Method called by IteratingCallback.iterate() to process the sub task.

Implementations must start the asynchronous execution of the sub task (if any) and return an appropriate action:

• IteratingCallback.Action.IDLE when no sub tasks are available for execution but the overall job is not completed yet
• IteratingCallback.Action.SCHEDULED when the sub task asynchronous execution has been started
• IteratingCallback.Action.SUCCEEDED when the overall job is completed

Specified by:

process in class IteratingCallback

Throws:

Exception - if the sub task processing throws

onRequestContent

protected void onRequestContent(Request proxyRequest,
                    HttpServletRequest request,
                    DeferredContentProvider provider,
                    byte[] buffer,
                    int offset,
                    int length,
                    Callback callback)

failed

public void failed(Throwable x)

Description copied from class: IteratingCallback

Invoked when the sub task fails. Subclasses that override this method must always remember to call super.failed(Throwable).

Specified by:

failed in interface Callback

Overrides:

failed in class IteratingCallback

Parameters:

x - the reason for the operation failure
