Class JRSaver

java.lang.Object

net.sf.jasperreports.engine.util.JRSaver

public final class JRSaver
extends Object

Utility class that can be used when serializable objects must be saved on disk or sent over the network through an output stream.

Both the JasperDesign and JasperReport classes implement the java.io.Serializable interface. This allows users to store their report templates as serialized objects either in their fully modifiable state (JasperDesign objects) or in their compiled form (JasperReport objects), using various methods exposed by this class.
