Examples of org.jgroups.blocks.MethodCall.invoke()

org.jgroups.blocks.MethodCall.invoke()
Invokes the method with the supplied arguments against the target object. If a method lookup is provided, it will be used. Otherwise, the default method lookup will be used. @param target - the object that you want to invoke the method on @return an object

        Target target = new Target();
        Object result = methodCall.invoke(target);
