Interface ProxyClassGenerator

All Known Implementing Classes:

SimpleProxyClassGenerator

public interface ProxyClassGenerator

Interface for proxy class generators. A proxy class generator is responsible for providing high level method to build a proxy class using BCEL. A typical proxy building using a proxy class generator is:

    generator.init();
 
    for each constructor:
       generator.addConstructor(constructor);
 
    for each method to proxify:
       generator.addMethod(method);
 
    bcelResult = generator.getJavaClass();

Method Summary

void	addConstructor(Constructor constructor) Add a new constructor to the proxy class.
void	addProxyMethod(Method method) Add a new proxified method.
JavaClass	getJavaClass() Get the BCEL class for the generated class.
void	init() Initialize the object for a new class generation.

Method Detail

init

public void init()

Initialize the object for a new class generation. Any class generated so far will be lost. This method must be called before addConstructor of addProxyMethod.

addConstructor

public void addConstructor(Constructor constructor)
                    throws IllegalStateException

Add a new constructor to the proxy class.

Parameters:

constructor -

Throws:

IllegalStateException - init wasn't called previously.

addProxyMethod

public void addProxyMethod(Method method)
                    throws IllegalStateException

Add a new proxified method.

Parameters:

method -

Throws:

IllegalStateException - init wasn't called previously.

getJavaClass

public JavaClass getJavaClass()
                       throws IllegalStateException

Get the BCEL class for the generated class.

Returns:

the class generated.

Throws:

IllegalStateException - init wasn't called previously.
