All Implemented Interfaces:

Closeable, AutoCloseable, ClassAnnotation, LoggableClassLoader

public class ServiceClassLoader
extends CustomURLClassLoader
implements ClassAnnotation

The ServiceClassLoader overrides getURLs(), ensuring all classes that need to be annotated with specific location(s) are returned appropriately

Constructor Details

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 Details
