protected Class defineClass(String name,
 byte[] b,
 CodeSource cs)
                     throws IOException

Override to weave class using WeavingAdaptor

Overrides:

defineClass in class ExtensibleURLClassLoader

Throws:

IOException

getBytes

protected byte[] getBytes(String name)
                   throws IOException

Override to find classes generated by WeavingAdaptor

Overrides:

getBytes in class ExtensibleURLClassLoader

Throws:

IOException

getAspectURLs

public URL[] getAspectURLs()

Implement method from WeavingClassLoader

Specified by:

getAspectURLs in interface WeavingClassLoader

Returns:

the aspects used for weaving classes.

acceptClass

public void acceptClass(String name,
 byte[] classBytes,
 byte[] weavedBytes)

Description copied from interface: GeneratedClassHandler

Accept class generated by WeavingAdaptor. The class loader should store the class definition in its local cache until called upon to load it.

Specified by:

acceptClass in interface GeneratedClassHandler

Parameters:

name - class name

classBytes - original class bytes

weavedBytes - woven class bytes
