MATLAB Object-Oriented Programming

Using Methods for Callbacks

The TestAnonyFcn class shows the use of an anonymous function with an additional

argument. The listener callback displays the inputs arguments to show how MATLAB calls

the callback method.

classdef TestAnonyFcn < handle

events

Update

end

methods

function obj = TestAnonyFcn

t = datestr(now);

addlistener(obj,'Update',@(src,evnt)obj.evntCb(src,evnt,t));

end

function triggerEvnt(obj)

notify(obj,'Update')

end

end

methods (Access = private)

function evntCb(~,~,evnt,varargin)

disp(['Number of inputs: ',num2str(nargin)])

disp(evnt.EventName)

disp(varargin{:})

end

end

end

Create an object and trigger the event by calling the triggerEvt method:

obj = TestAnonyFcn;

obj.triggerEvnt;

Number of inputs: 4
