Imports
java.io.IOException, .InputStream, com.sun.org.apache.bcel.internal.classfile.ClassParser, .JavaClass, .Utility, java.lang.ref.SoftReference, java.util.HashMap, .Map
This repository is used in situations where a Class is created outside the realm of a ClassLoader. Classes are loaded from the file systems using the paths specified in the given class path. By default, this is the value returned by ClassPath.getClassPath().

This repository uses a factory design, allowing it to maintain a collection of different classpaths, and as such It is designed to be used as a singleton per classpath.

public JavaClass loadClass(final Class<?> clazz) throws ClassNotFoundException

Implements com.sun.org.apache.bcel.internal.util.Repository.loadClass.

Finds the JavaClass object for a runtime Class object. If a class with the same name is already in this Repository, the Repository version is returned. Otherwise, getResourceAsStream() is called on the Class object to find the class's representation. If the representation is found, it is added to the Repository.

Parameters
clazz:Class<?>

the runtime Class object

Returns:JavaClass

JavaClass object for given runtime class

Annotations
@Override
Exceptions
ClassNotFoundException:
if the class is not in the Repository, and its representation could not be found
