Class MethodProxy

  • java.lang.Object
    • org.springframework.cglib.proxy.MethodProxy


  • public class MethodProxy
    extends java.lang.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.

      For internal use by Enhancer only; see the FastMethod class for similar functionality.
      static MethodProxy find(java.lang.Class type, org.springframework.cglib.core.Signature sig)
      Return the MethodProxy used when intercepting the method matching the given signature.
      org.springframework.cglib.core.Signature getSignature()
      Return the signature of the proxied method.
      int getSuperIndex()
      Return the FastClass method index for the method used by invokeSuper(java.lang.Object, java.lang.Object[]).
      java.lang.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.
      java.lang.Object invoke(java.lang.Object obj, java.lang.Object[] args)
      Invoke the original method, on a different object of the same type.
      java.lang.Object invokeSuper(java.lang.Object obj, java.lang.Object[] args)
      Invoke the original (super) method on the specified object.

      • getSignature

        public org.springframework.cglib.core.Signature getSignature()
        Return the signature of the proxied method.
      • getSuperName

        public java.lang.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.
      • find

        public static MethodProxy find(java.lang.Class type,
                                       org.springframework.cglib.core.Signature sig)
        Return the MethodProxy used when intercepting the method matching the given signature.
        Parameters:
        type - the class generated by Enhancer
        sig - the signature to match
        Returns:
        the MethodProxy instance, or null if no applicable matching method is found
        Throws:
        java.lang.IllegalArgumentException - if the Class was not created by Enhancer or does not use a MethodInterceptor
      • invoke

        public java.lang.Object invoke(java.lang.Object obj,
                                       java.lang.Object[] args)
                                throws java.lang.Throwable
        Invoke the original method, on a different object of the same type.
        Parameters:
        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
        Throws:
        java.lang.Throwable - the bare exceptions thrown by the called method are passed through without wrapping in an InvocationTargetException
        See Also:
        MethodInterceptor.intercept(java.lang.Object, java.lang.reflect.Method, java.lang.Object[], org.springframework.cglib.proxy.MethodProxy)
      • invokeSuper

        public java.lang.Object invokeSuper(java.lang.Object obj,
                                            java.lang.Object[] args)
                                     throws java.lang.Throwable
        Invoke the original (super) method on the specified object.
        Parameters:
        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
        Throws:
        java.lang.Throwable - the bare exceptions thrown by the called method are passed through without wrapping in an InvocationTargetException
