Class StubGenerator

java.lang.Object

javassist.tools.rmi.StubGenerator

All Implemented Interfaces:

Translator

public class StubGenerator
extends java.lang.Object
implements Translator

A stub-code generator. It is used for producing a proxy class.

The proxy class for class A is as follows:

public class A implements Proxy, Serializable {
   private ObjectImporter importer;
   private int objectId;
   public int _getObjectId() { return objectId; }
   public A(ObjectImporter oi, int id) {
     importer = oi; objectId = id;
   }

   ... the same methods that the original class A declares ...
 }

Instances of the proxy class is created by an ObjectImporter object.

Method Detail

start

public void start(ClassPool pool)
           throws NotFoundException

Initializes the object. This is a method declared in javassist.Translator.

Specified by:

start in interface Translator

Parameters:

pool - the ClassPool that this translator should use.

Throws:

NotFoundException - if a CtClass cannot be found.

See Also:

Translator.start(ClassPool)

onLoad

public void onLoad(ClassPool pool,
                   java.lang.String classname)

Does nothing. This is a method declared in javassist.Translator.

Specified by:

onLoad in interface Translator

Parameters:

pool - the ClassPool that this translator should use.

classname - the name of the class being loaded.

See Also:

Translator.onLoad(ClassPool,String)

isProxyClass

public boolean isProxyClass(java.lang.String name)

Returns true if the specified class is a proxy class recorded by makeProxyClass().

Parameters:

name - a fully-qualified class name

makeProxyClass

public boolean makeProxyClass(java.lang.Class clazz)
                       throws CannotCompileException,
                              NotFoundException

Makes a proxy class. The produced class is substituted for the original class.

Parameters:

clazz - the class referenced through the proxy class.

Returns:

false if the proxy class has been already produced.

Throws:

CannotCompileException
