当Parmae​​ter是另一个类的实例时调用方法-Java

Question

Ill try to make it short. I want to iterate through the methods of a class via "getMethods()". Now when the method has a Parameter which is an instance of the "Event" class, it should be invoked.

Example Method:

private void onEvent(ExampleEvent event) {...]

"ExampleEvent" is an instance of the "Event" class.

Help is appreciated!

Answer 1

You want to use getParameterTypes() instead of getParameters() . If you want to match a parameter type to a parameter name, simply index the two arrays the same.

Answer 2

Something Like this, its been awhile since i wrote in java but This something like this should work

Method[] methods = Class.getMethods();
    List<Method> methodsWithEvent = new List<Method>();
    for(Method method : methods){
       Class[] params = method.getParameterTypes();
       for(Class class : params)
          if(typeof(class) == typeof(ExampleEvent))
              methodsWithEvents.add(method);

    }
