getInstance

public static Interceptor getInstance()

newPrototypeClass

public static <T> java.lang.Class<T> newPrototypeClass(java.lang.Class<T> cls,
                                                       T prototype)

Creates a prototype class. When an instance is created, its bean properties are copied from the prototype. Afterward, the instance functions independently from the prototype.

Type Parameters:

T - type of prototype

Parameters:

cls - prototype class

prototype - prototype instance

Returns:

byte manipulated prototype class

newSingletonClass

public static <T> java.lang.Class<T> newSingletonClass(java.lang.Class<T> cls,
                                                       T singleton)

newSingletonClass

public static <T> java.lang.Class<T> newSingletonClass(java.lang.Class<T> cls,
                                                       T singleton,
                                                       InterceptorListener listener)

newInterceptor

public <T> T newInterceptor(T instance,
                            InterceptorHandler handler)

Creates an interceptor for an instance. All calls for the interceptor, except for methods declared in Object, are forwarded to the handler.

Type Parameters:

T - type of instance

Parameters:

instance - the instance of which calls are to be intercepted

handler - handler of intercepted calls

Returns:

an instance of interceptor

newInterceptor

public <T> T newInterceptor(T instance,
                            InterceptorHandler handler,
                            InterceptorListener listener)

newInstance

public <T> T newInstance(java.lang.Class cls,
                         InterceptorHandler handler)

Create an interceptor just like the newInterceptor method. However, the instance is set to cls.newInstance().

Type Parameters:

T - type of instance

Parameters:

cls - instance class

handler - handler

Returns:

byte enhanced instance.

newInstance

public <T> T newInstance(java.lang.Class cls,
                         InterceptorHandler handler,
                         InterceptorListener listener)

createClass

protected java.lang.Class createClass(java.lang.Class cls)

isProxyObject

public static boolean isProxyObject(java.lang.Object proxyObject)

cloneProxyObject

getInterceptorHandler

public static <T extends InterceptorHandler> T getInterceptorHandler(java.lang.Object proxyObject)

setInterceptorHandler

public static <T extends InterceptorHandler> void setInterceptorHandler(java.lang.Object proxyObject,
                                                                        T handler)

getInterceptorListener

public static <T extends InterceptorListener> T getInterceptorListener(java.lang.Object proxyObject)

setInterceptorListener

public static <T extends InterceptorListener> void setInterceptorListener(java.lang.Object proxyObject,
                                                                          T handler)
