Method Detail

getInstance

public static Interceptor getInstance()

getInitialCapacity

public int getInitialCapacity()

setInitialCapacity

public void setInitialCapacity(int initialCapacity)

getMaximumSize

public int getMaximumSize()

setMaximumSize

public void setMaximumSize(int maximumSize)

getExpiration

public long getExpiration()

setExpiration

public void setExpiration(long expiration)

initialize

public void initialize()

newPrototypeClass

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

newPrototypeClass

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

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

singletonClassBuilder

public <T> SingletonClassBuilder<T> singletonClassBuilder(java.lang.Class<T> cls,
                                                          T singleton)

newSingletonClass

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

runAnonymous

public <T> void runAnonymous(T target,
                             T anonymous)

runAnonymous

public <T> void runAnonymous(java.lang.invoke.MethodHandles.Lookup lookup,
                             T target,
                             T anonymous)

Trying to emulate Groovy's with block. The constructor must be a no-arg. X x = ...; runAnonymous(x, new X() {{ setName(...); setInt(...); }} setName and setInt would be called on x.

interceptorBuilder

public <T> InterceptorBuilder<T> interceptorBuilder(T instance,
                                                    InterceptorHandler handler)

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

instanceBuilder

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

newInstance

public <T> T newInstance(java.lang.Class<T> 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.

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)
