org.apache.bcel.util.MemorySensitiveClassPathRepository

org.apache.bcel.util.SyntheticRepository

All Implemented Interfaces:

Repository

public class SyntheticRepository
extends MemorySensitiveClassPathRepository

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.

loadClass

public JavaClass loadClass(String className)
                    throws ClassNotFoundException

Finds a JavaClass object by name. If it is already in this Repository, the Repository version is returned. Otherwise, the Repository's classpath is searched for the class (and it is added to the Repository if found).

Specified by:

loadClass in interface Repository

Parameters:

className - the name of the class

Returns:

the JavaClass object

Throws:

ClassNotFoundException - if the class is not in the Repository, and could not be found on the classpath

loadClass

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

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.

Specified by:

loadClass in interface Repository

Parameters:

clazz - the runtime Class object

Returns:

JavaClass object for given runtime class

Throws:

ClassNotFoundException - if the class is not in the Repository, and its representation could not be found
