java.lang.Object

org.apache.bcel.util.MemorySensitiveClassPathRepository

All Implemented Interfaces:

Repository

Direct Known Subclasses:

SyntheticRepository

public class MemorySensitiveClassPathRepository
extends Object

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 holds onto classes with SoftReferences, and will reload as needed, in cases where memory sizes are important.

Method Detail

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(String className)

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

Specified by:

findClass in interface Repository

clear

public void clear()

Clear all entries from cache.

Specified by:

clear in interface Repository

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
