Giving a method name as a parameter
Posted on 2007-11-29
Mainly asking the following for java, but also interested how it applies to C# too
I have a "timer" class called Reminder which does some processing and run a method on another object every x seconds. (a new thread is created each time we create an instance of the class)
From within the main object of my application I create a new Reminder object, giving to its constructor a reference to the current object:
the Reminder object will call a method ( for example doSomething() ) on the main object, every x seconds.
Is there any way to specify what method to be called on the main object from the Reminder object when
I create the Reminder object, instead of having to specify it withing the Reminder class ?
For example, when I create the Reminder object to give the method to be called as a parameter
in the constructor. Something like:
new Reminder(this, doSomething())
this way, I will be able to use the same Reminder class in many different situations within the application,
and be able to create many Reminder objects that will call different methods when the time is up, without having to re-write the Reminder class.
and b.t.w. is there a way (a keyword or something) to get a reference to the object from where the current object was created ? (so I don't have to give the "this" as a parameter to the Reminder constructor)
