Method Detail

invoke

public final Object invoke(Object self,
                           Method thisMethod,
                           Method proceed,

Description copied from interface: MethodHandler

Is called when a method is invoked on a proxy instance associated with this handler. This method must process that method invocation.

Specified by:

invoke in interface MethodHandler

Parameters:

self - the proxy instance.

thisMethod - the overridden method declared in the super class or interface.

proceed - the forwarder method for invoking the overridden method. It is null if the overridden method is abstract or declared in the interface.

args - an array of objects containing the values of the arguments passed in the method invocation on the proxy instance. If a parameter type is a primitive type, the type of the array element is a wrapper class.

Returns:

the resulting value of the method invocation.

Throws:

Throwable - if the method invocation fails.

doInvoke

protected abstract Object doInvoke(Object self,
                                   Method thisMethod,
                                   Method proceed,
                                   Object[] args)
                            throws Throwable

Throws:

Throwable
