Class IntermediateListener

java.lang.Object

org.rdfhdt.hdt.util.listener.IntermediateListener

All Implemented Interfaces:

ProgressListener

public class IntermediateListener
extends Object
implements ProgressListener

Provides notifications by dividing an overall task in subtasks. Call setRange() with the estimated percent of the overall task that the subtask will take (i.e. 20-40%). Then call the subtask providing the IntermediateListener as Callback. The IntermediateListener will translate the notifications of the subtask (in the 0-100 range) to the range supplied (20-40) by using linear interpolation.
