Constructor Detail

BCELClassLoader

public BCELClassLoader(java.lang.ClassLoader parent)

Creates a new class loader using the specified parent class loader for delegation.

Parameters:

parent - the parent class loader.

Method Detail

addClass

public void addClass(java.lang.String className,
                     byte[] bytecode)

Adds a new class data to this class loader. After a call to this method, this class loader is able to find and define the new specified class, if parameters are valid.

Parameters:

className - the complete class name. Must be not null.

bytecode - the bytecode of the new class. Must be not null and it is considered all its content, starting from offset 0 and ending at offset bytecode.length - 1. It is recommended that the caller doesn't modify its content, because this array is cached as is, without cloning it.

findClass

protected java.lang.Class<?> findClass(java.lang.String name)
                                throws java.lang.ClassNotFoundException

Finds the class with the specified binary name, searching in the pool of classes added by the addClass(String, byte[]) method.

Overrides:

findClass in class java.lang.ClassLoader

Parameters:

name - the binary name of the class.

Returns:

the resulting Class object.

Throws:

java.lang.ClassNotFoundException - if the class could not be found, because it's not been added to this class loader.
