| java.lang.reflect.InvocationHandler |
Class Overview
Implementors of this interface dispatch methods invoked on proxy instances.
Public Methods
Handles the method which was originally invoked on the proxy instance. A
typical usage pattern follows below:
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
//do some processing before the method invocation
//invoke the method
Object result = method.invoke(proxy, args);
//do some processing after the method invocation
return result;
}
Parameters
| proxy
| the proxy instance on which the method was invoked |
| method
| the method invoked on the proxy instance |
| args
| an array of objects containing the parameters passed to the
method, or null if no arguments are expected.
Primitive types are wrapped in the appropriate wrapper type |
Returns
- the result of executing the method. Primitive types need to be
wrapped in the appropriate wrapper type
Throws
| Throwable
| the exception to throw from the invoked method on the proxy.
The exception must match one of the declared exception types
of the invoked method or any unchecked exception type. If not
then an UndeclaredThrowableException is thrown
