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.

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

For internal use by Enhancer only; see the org.springframework.cglib.reflect.FastMethod class for similar functionality.

public static MethodProxy

Returns:

the MethodProxy instance, or null if no applicable matching method is found
find(Class<T>
the class generated by Enhancer
type, Signature
the signature to match
sig)

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

pack-priv FastClass
getFastClass()

public Signature
getSignature()

Return the signature of the proxied method.

pack-priv FastClass
getSuperFastClass()

public int
getSuperIndex()

Return the org.springframework.cglib.reflect.FastClass method index for the method used by invokeSuper.

public String
getSuperName()

Return the name of the synthetic method created by CGLIB which is used by invokeSuper to invoke the superclass (non-intercepted) method implementation.

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

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

public static MethodProxy find(Class<T> type, Signature sig)

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

Parameters
type:Class<T>

the class generated by Enhancer

sig:Signature

the signature to match

Returns:MethodProxy

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

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

public int getSuperIndex()

Return the org.springframework.cglib.reflect.FastClass method index for the method used by invokeSuper. This index uniquely identifies the method within the generated proxy, and therefore can be useful to reference external metadata.

public String getSuperName()

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

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

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

Parameters
obj:Object

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:Object[]

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

Exceptions
Throwable:
the bare exceptions thrown by the called method are passed through without wrapping in an InvocationTargetException
See Also
MethodInterceptor#intercept
invokeSuperback to summary
public Object invokeSuper(Object obj, Object[] args) throws Throwable

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

Parameters
obj:Object

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

args:Object[]

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