Class MuleUrlStreamHandlerFactory

java.lang.Object

org.mule.runtime.module.artifact.api.classloader.net.MuleUrlStreamHandlerFactory

All Implemented Interfaces:

URLStreamHandlerFactory

@NoInstantiate
public final class MuleUrlStreamHandlerFactory
extends Object
implements URLStreamHandlerFactory

A factory for loading URL protocol handlers. This factory is necessary to make Mule work in cases where the standard approach using system properties does not work, e.g. in application servers or with maven's surefire tests.

Client classes can register a subclass of URLStreamHandler for a given protocol. This implementation first checks its registered handlers before resorting to the default mechanism.

Method Detail

installUrlStreamHandlerFactory

public static void installUrlStreamHandlerFactory()

Install an instance of this class as UrlStreamHandlerFactory. This may be done exactly once as URL will throw an Error on subsequent invocations.

This method takes care that multiple invocations are possible, but the UrlStreamHandlerFactory is installed only once.

registerHandler

public static void registerHandler(String protocol,
                                   URLStreamHandler handler)

createURLStreamHandler

public URLStreamHandler createURLStreamHandler(String protocol)
