Class InterfaceMaker

java.lang.Object
  net.sf.cglib.core.AbstractClassGenerator
      net.sf.cglib.proxy.InterfaceMaker

All Implemented Interfaces:

ClassGenerator

public class InterfaceMaker
extends AbstractClassGenerator

Generates new interfaces at runtime. By passing a generated interface to the Enhancer's list of interfaces to implement, you can make your enhanced classes handle an arbitrary set of method signatures.

Constructor Detail

InterfaceMaker

public InterfaceMaker()

Create a new InterfaceMaker. A new InterfaceMaker object should be used for each generated interface, and should not be shared across threads.

Method Detail

add

public void add(Signature sig,
                org.objectweb.asm.Type[] exceptions)

Add a method signature to the interface.

Parameters:

sig - the method signature to add to the interface

exceptions - an array of exception types to declare for the method

add

public void add(java.lang.reflect.Method method)

Add a method signature to the interface. The method modifiers are ignored, since interface methods are by definition abstract and public.

Parameters:

method - the method to add to the interface

add

public void add(java.lang.Class clazz)

Add all the public methods in the specified class. Methods from superclasses are included, except for methods declared in the base Object class (e.g. getClass, equals, hashCode).

Parameters:

class - the class containing the methods to add to the interface

create

public java.lang.Class create()

Create an interface using the current set of method signatures.

firstInstance

protected java.lang.Object firstInstance(java.lang.Class type)

Specified by:

nextInstance

protected java.lang.Object nextInstance(java.lang.Object instance)

generateClass

public void generateClass(org.objectweb.asm.ClassVisitor v)
                   throws java.lang.Exception

Throws:
