Class AccumulatingProgressInputStream

java.lang.Object

java.io.InputStream

de.esprit.appsuite.io.AccumulatingProgressInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class AccumulatingProgressInputStream
extends java.io.InputStream

This is a special stream that allows to change the actually read stream from outside. All bytes read from any current stream are accumulated until the totalBytes are read and progress is fired accordingly. This class is used i.e. for reading many files and providing a continuous progress notification across all.
