Constructor Detail

LaunchedURLClassLoader

public LaunchedURLClassLoader(URL[] urls,
                              ClassLoader parent)

Create a new LaunchedURLClassLoader instance.

Parameters:

urls - the URLs from which to load classes and resources

parent - the parent class loader for delegation

Method Detail

getResource

public URL getResource(String name)

Gets the resource with the given name. Unlike a standard ClassLoader, this method will first search the root class loader. If the resource is not found, this method will call findResource(String).

Overrides:

getResource in class ClassLoader

findResource

public URL findResource(String name)

Overrides:

findResource in class URLClassLoader

findResources

public Enumeration<URL> findResources(String name)
                               throws IOException

Overrides:

findResources in class URLClassLoader

Throws:

IOException

getResources

public Enumeration<URL> getResources(String name)
                              throws IOException

Gets the resources with the given name. Returns a combination of the resources found by findResources(String) and from getResources(String) on the root class loader, if any.

Overrides:

getResources in class ClassLoader

Throws:

IOException

loadClass

protected Class<?> loadClass(String name,
                             boolean resolve)
                      throws ClassNotFoundException

Attempt to load classes from the URLs before delegating to the parent loader.

Overrides:

loadClass in class ClassLoader

Throws:

ClassNotFoundException
