Method Details

getInvocationType

public Invocable.InvocationType getInvocationType()

Specified by:

getInvocationType in interface Invocable

Returns:

The InvocationType of this object

window

public void window(HTTP2Stream stream,
 WindowUpdateFrame frame)

prepend

public boolean prepend(HTTP2Session.Entry entry)

append

public boolean append(HTTP2Session.Entry entry)

append

public boolean append(List<HTTP2Session.Entry> list)

public int getFrameQueueSize()

process

protected IteratingCallback.Action process()
                                    throws Throwable

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:

Throwable - if the sub-task processing throws

onSuccess

protected void onSuccess()

Description copied from class: IteratingCallback

Invoked when one task has completed successfully, either by the caller thread or by the processing thread. This invocation is always serialized w.r.t the execution of IteratingCallback.process().

This method is not invoked when a call to IteratingCallback.abort(Throwable) is made before the IteratingCallback.succeeded() callback happens.

Overrides:

onSuccess in class IteratingCallback

onCompleteSuccess

protected void onCompleteSuccess()

Description copied from class: IteratingCallback

Invoked when the overall task has completed successfully.

Overrides:

onCompleteSuccess in class IteratingCallback

See Also:

• IteratingCallback.onCompleteFailure(Throwable)

onCompleteFailure

protected void onCompleteFailure(Throwable x)

Description copied from class: IteratingCallback

Invoked when the overall task has completed with a failure.

Overrides:

onCompleteFailure in class IteratingCallback

Parameters:

x - the throwable to indicate cause of failure

See Also:

• IteratingCallback.onCompleteSuccess()

terminate

public void terminate(Throwable cause)

dump

public String dump()

Specified by:

dump in interface Dumpable

dump

public void dump(Appendable out,
 String indent)
          throws IOException

Description copied from interface: Dumpable

Dump this object (and children) into an Appendable using the provided indent after any new lines. The indent should not be applied to the first object dumped.

Specified by:

dump in interface Dumpable

Parameters:

out - The appendable to dump to

indent - The indent to apply after any new lines.

Throws:

IOException - if unable to write to Appendable

toString

public String toString()

Overrides:

toString in class IteratingCallback
