Events Listening, Callback functions

Hi, for my project I've got objects which should have thier listener callback function executed a certain among of times (up to 12 times) befor performing any other computations.

Can someone give me any guidance how to achieve this??

thanks,

What are "objects" in your case?

Hi simon,

my objects can be defined as following:

classdef object < handle

properties
Link[10] % array obj objects link
end

methods 
function obj = objects(objx) %objx is array of objects of type objects1
if nargin ~=0
addlistener(objx,'BS_CH_CONFIRM',@callbackconfirm);
addlistener(objx,'BS_CHANNEL_REQUEST';@callbackrequest);
end
end
........
end

now Assume we have six instance of class objects listening to each other. obj(6) = object; and obj(1) = objects([obj2-6]),obj(2)=objects([obj1,3-6]),obj(3) = objects([obj1,2,4-6]) and so on. When obj(1) echo if noone is been using link(2). all the other should reply depending on thier status, either immediately if themself currently haven't initiate a request or postpone if they do. the Reply appends information about status of their using links properties (link(2) in our case). Just after thier reply can obj(1) check for which property it should ask again. then they should use dictinct link properties' object. Now how do I know if all the other have reply? or set any timeout for reply notification.

thanks
