Class URLStreamHandlerFactoryInstaller

java.lang.Object
  org.nuxeo.common.utils.URLStreamHandlerFactoryInstaller

public class URLStreamHandlerFactoryInstaller
extends Object

Used to force installation of URLStreamHandlerFactory as the default mechanism in Java is failing to set a new factory if one was already set.

This class provides the capability to stack any number of factories - each factory having precedence over the last one.

Thus, when querying for a URL protocol handler all factories will be asked in turn (from the newest one to the older one) until a stream handler is obtained.

Contains some code from Eclipse Framework class.
