Methods Summary
public voidclear()
Clear all entries from cache.

    loadedClasses.clear();
public com.sun.org.apache.bcel.internal.classfile.JavaClassfindClass(java.lang.String className)
Find an already defined JavaClass.

    if ( loadedClasses.containsKey( className )) {
      return (JavaClass) loadedClasses.get( className );
    } else {
      return null;
    }
public com.sun.org.apache.bcel.internal.classfile.JavaClassloadClass(java.lang.String className)
Lookup a JavaClass object from the Class Name provided.

    String classFile = className.replace('.", '/");

    JavaClass RC = findClass( className );
    if (RC != null) { return RC; }

    try {
      InputStream is = 
	loader.getResourceAsStream( classFile + ".class" );
	    
      if(is == null) {
	throw new ClassNotFoundException(className + " not found.");
      }

      ClassParser parser = new ClassParser( is, className );
      RC = parser.parse();
	    
      storeClass( RC );

      return RC;
    } catch (IOException e) {
      throw new ClassNotFoundException( e.toString() );

    return loadClass(clazz.getName());
public voidremoveClass(com.sun.org.apache.bcel.internal.classfile.JavaClass clazz)
Remove class from repository

    loadedClasses.remove(clazz.getClassName());
public voidstoreClass(com.sun.org.apache.bcel.internal.classfile.JavaClass clazz)
Store a new JavaClass into this Repository.
