Class ChainedProgressReporter

All Implemented Interfaces:

public class ChainedProgressReporter
extends Object
implements ProgressReporter
An implementation of the ProgressReporter interface that chains to another progress reporter while recalculating the percentage values. This class is useful when you call several methods in a row that each of them outputs progress messages between 0 and 100 percent. Use this progress reporter to change the scale so that the first method output values between 0 and 20, the next between 20 and 50, and so on.
