Method Details

getDescriptor

public QueueDescriptor<?> getDescriptor()

Description copied from interface: Queue

Returns the descriptor which was used to create this queue.

Specified by:

getDescriptor in interface Queue

Returns:

descriptor of this queue

See Also:

• QueueCollection.getQueue(QueueDescriptor)
• QueueDescriptor.createQueue(QueueCollection)

createProcessor

protected abstract GraphQueue.Processor createProcessor()

process

public boolean process(int[] segments)
                throws RuntimeModelException

Description copied from interface: Queue

Processes all queued tasks. This method is invoked by QueueCollection.process(int[]).

Specified by:

process in interface Queue

Returns:

true iff the execution of tasks resulted in modifications to the Graph

Throws:

RuntimeModelException - if some error occurs during execution

clearSegmentsToExcludeImpl

protected void clearSegmentsToExcludeImpl(int[] segs)

markSegment

resetToSegment

public void resetToSegment(int n)

Specified by:

clear

public void clear()

Description copied from interface: Queue

Clears the queue. This is invoked by the QueueCollection in order to reuse the queue for a new transformation step.

Specified by:
