Method Detail

onDataAvailable

public void onDataAvailable()

Specified by:

onDataAvailable in interface javax.servlet.ReadListener

onAllDataRead

public void onAllDataRead()

Specified by:

onAllDataRead in interface javax.servlet.ReadListener

onError

public void onError(java.lang.Throwable t)

Specified by:

onError in interface javax.servlet.ReadListener

process

protected IteratingCallback.Action process()
                                    throws java.lang.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

Returns:

the appropriate Action

Throws:

java.lang.Exception

onRequestContent

protected void onRequestContent(javax.servlet.http.HttpServletRequest request,
                                Request proxyRequest,
                                AsyncRequestContent content,
                                byte[] buffer,
                                int offset,
                                int length,
                                Callback callback)

failed

public void failed(java.lang.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
