类 MethodProxy

java.lang.Object

cn.taketoday.bytecode.proxy.MethodProxy

public class MethodProxy
extends Object

Classes generated by Enhancer pass this object to the registered MethodInterceptor objects when an intercepted method is invoked. It can be used to either invoke the original method, or call the same method on a different object of the same type.

方法详细资料

create

public static MethodProxy create(Class c1,
 Class c2,
 String desc,
 String name1,
 String name2)

For internal use by Enhancer only; see the MethodAccess class for similar functionality.

getSignature

public MethodSignature getSignature()

Return the signature of the proxied method.

getSuperName

public String getSuperName()

Return the name of the synthetic method created by CGLIB which is used by invokeSuper(java.lang.Object, java.lang.Object[]) to invoke the superclass (non-intercepted) method implementation. The parameter types are the same as the proxied method.

getSuperIndex

public int getSuperIndex()

Return the MethodAccess method index for the method used by invokeSuper(java.lang.Object, java.lang.Object[]). This index uniquely identifies the method within the generated proxy, and therefore can be useful to reference external metadata.

• getSuperName()

find

public static MethodProxy find(Class type,
 MethodSignature sig)

Return the MethodProxy used when intercepting the method matching the given signature.

参数:

type - the class generated by Enhancer

sig - the signature to match

返回:

the MethodProxy instance, or null if no applicable matching method is found

抛出:

IllegalArgumentException - if the Class was not created by Enhancer or does not use a MethodInterceptor

invoke

public Object invoke(Object obj,
 Object[] args)
              throws Throwable

Invoke the original method, on a different object of the same type.

参数:

obj - the compatible object; recursion will result if you use the object passed as the first argument to the MethodInterceptor (usually not what you want)

args - the arguments passed to the intercepted method; you may substitute a different argument array as long as the types are compatible

抛出:

Throwable - the bare exceptions thrown by the called method are passed through without wrapping in an InvocationTargetException

invokeSuper

public Object invokeSuper(Object obj,
 Object[] args)
                   throws Throwable

Invoke the original (super) method on the specified object.

参数:

obj - the enhanced object, must be the object passed as the first argument to the MethodInterceptor

args - the arguments passed to the intercepted method; you may substitute a different argument array as long as the types are compatible

抛出:

Throwable - the bare exceptions thrown by the called method are passed through without wrapping in an InvocationTargetException
