Method Detail

addShutdownListener

public void addShutdownListener(ShutdownListener listener)

Description copied from interface: ArtifactClassLoader

Adds a shutdown listener to the class loader. This listener will be invoked synchronously right before the class loader is disposed and closed.

Specified by:

addShutdownListener in interface ArtifactClassLoader

dispose

public void dispose()

Description copied from class: GoodCitizenClassLoader

A workaround for http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5041014

Specified by:

dispose in interface DisposableClassLoader

Overrides:

dispose in class GoodCitizenClassLoader

findLocalResource

public URL findLocalResource(String resourceName)

Description copied from interface: LocalResourceLocator

This method finds a resource in the local environment for this artifact, if the resource is not found and the artifact has a parent artifact then the operation is resolved by that parent, if there is no parent, the resources is searched in the global environment.

Specified by:

findLocalResource in interface LocalResourceLocator

Parameters:

resourceName - name of the resource to find.

Returns:

the resource URL, null if it doesn't exists.

getLocalResourceLocations

protected abstract String[] getLocalResourceLocations()
