Class AsynchronousFillHandle

java.lang.Object

net.sf.jasperreports.engine.fill.BaseFillHandle

net.sf.jasperreports.engine.fill.AsynchronousFillHandle

All Implemented Interfaces:

FillHandle

public class AsynchronousFillHandle
extends BaseFillHandle

Class used to perform report filling asychronously.

An instance of this type can be used as a handle to an asychronous fill process. The main benefit of this method is that the filling process can be cancelled.
