类 Proxy

cn.taketoday.bytecode.proxy.Proxy

所有已实现的接口:

Serializable

public class Proxy
extends Object
implements Serializable

This class is meant to be used as replacement for java.lang.reflect.Proxy under JDK 1.2. There are some known subtle differences:

• The exceptions returned by invoking getExceptionTypes on the Method passed to the invoke method are the exact set that can be thrown without resulting in an UndeclaredThrowableException being thrown.
• UndeclaredThrowableException is used instead of java.lang.reflect.UndeclaredThrowableException.

方法详细资料

getInvocationHandler

public static InvocationHandler getInvocationHandler(Object proxy)

getProxyClass

public static Class<?> getProxyClass(ClassLoader loader,
 Class<?>... interfaces)

isProxyClass

public static boolean isProxyClass(Class<?> cl)

newProxyInstance

public static Object newProxyInstance(ClassLoader loader,
 Class<?>[] interfaces,
 InvocationHandler h)

Returns an instance of a proxy class for the specified interfaces that dispatches method invocations to the specified invocation handler.

Proxy.newProxyInstance throws IllegalArgumentException for the same reasons that Proxy.getProxyClass does.

参数:

loader - the class loader to define the proxy class

interfaces - the list of interfaces for the proxy class to implement

h - the invocation handler to dispatch method invocations to

返回:

a proxy instance with the specified invocation handler of a proxy class that is defined by the specified class loader and that implements the specified interfaces

抛出:

NullPointerException - if the interfaces array argument or any of its elements are null, or if the invocation handler, h, is null
