Class SyntheticRepository

java.lang.Object

org.apache.bcel.util.SyntheticRepository

All Implemented Interfaces:

java.io.Serializable, Repository

public class SyntheticRepository
extends java.lang.Object
implements Repository

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().
It is designed to be used as a singleton, however it can also be used with custom classpaths.

Method Detail

getInstance

public static SyntheticRepository getInstance()

getInstance

public static SyntheticRepository getInstance(ClassPath classPath)

storeClass

public void storeClass(JavaClass clazz)

Store a new JavaClass instance into this Repository.

Specified by:

storeClass in interface Repository

removeClass

public void removeClass(JavaClass clazz)

Remove class from repository

Specified by:

removeClass in interface Repository

findClass

public JavaClass findClass(java.lang.String className)

Find an already defined (cached) JavaClass object by name.

Specified by:

findClass in interface Repository

loadClass

public JavaClass loadClass(java.lang.String className)
                    throws java.lang.ClassNotFoundException

Find 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:

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

loadClass

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

Find 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:

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