Class CloseableJarHandlerFactory

java.lang.Object

com.google.gwt.dev.url.CloseableJarHandlerFactory

All Implemented Interfaces:

URLStreamHandlerFactory

public class CloseableJarHandlerFactory
extends Object
implements URLStreamHandlerFactory

A factory that constructs URL Stream Handlers and extends Jar protocol handling by making it possible to close all InputStreams for a given Zip file.

This closing functionality makes it possible to run untrusted plugin code (for example Generators) and still guarantee that there will be no accidental attempts to read from old and deleted Zip files using stale InputStreams.
