Method Details

onDataAvailable

public void onDataAvailable()

Specified by:

onDataAvailable in interface jakarta.servlet.ReadListener

onAllDataRead

public void onAllDataRead()

Specified by:

onAllDataRead in interface jakarta.servlet.ReadListener

onError

public void onError(Throwable t)

Specified by:

onError in interface jakarta.servlet.ReadListener

process

protected IteratingCallback.Action process()
                                    throws Exception

Description copied from class: IteratingCallback

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

Implementations must initiate 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:

Exception

onRequestContent

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

failed

public void failed(Throwable x)

Description copied from class: IteratingCallback

Method to invoke when the asynchronous sub-task fails, or to fail the overall asynchronous task and therefore terminate the iteration.

Subclasses that override this method must always remember to call super.failed(Throwable).

Eventually, IteratingCallback.onCompleteFailure(Throwable) is called, either by the caller thread or by the processing thread.

Specified by:

failed in interface Callback

Overrides:

failed in class IteratingCallback

Parameters:

x - the reason for the operation failure
