public ArrayClassLoader()

Default constructor

Method Detail

setBytecodeSource

public void setBytecodeSource(BytecodeSource bs)

Sets the reference to the original bytecode loader. By default, the value is null. If the value is null, then there is the possibility for a link error.

addClass

public void addClass(String name,
                     byte[] bytecode)

Add a new class to the internal list.

loadClass

public Class loadClass(String name,
                       boolean resolve)
                throws ClassNotFoundException

Overrides:

loadClass in class ClassLoader

getBytecode

protected byte[] getBytecode(String className)

Retrieves the internal bytecode for the given class. If not known, then will attempt to pass it to the bytecode source.

Parameters:

className - a non-null class name.
