Constructor Detail

ServiceClassLoader

public ServiceClassLoader(String name,
                          URL[] searchPath,
                          ClassAnnotator annotator,
                          ClassLoader parent)

Constructs a new ServiceClassLoader for the specified URLs having the given parent. The constructor takes two sets of URLs. The first set is where the class loader loads classes from, the second set is what it returns when getURLs() is called.

Parameters:

searchPath - Array of URLs to search for classes

annotator - Array of URLs to use for the codebase

parent - Parent ClassLoader to delegate to

Method Detail

public CodeChangeClassLoadersManager getCodeChangeClassLoadersManager()

getClassAnnotator

public ClassAnnotator getClassAnnotator()

Get the ClassAnnotator created at construction time

getURLs

public URL[] getURLs()

Get the URLs to be used for class annotations as determined by the ClassAnnotator

Overrides:

getURLs in class URLClassLoader

Exception

getSearchPath

public URL[] getSearchPath()

Get the search path of URLs for loading classes and resources

Overrides:

getSearchPath in class CustomURLClassLoader

getClassAnnotation

public String getClassAnnotation()

Get the class annotations as determined by the ClassAnnotator

Specified by:
