MagicListener 1.0

MagicListener constructor creates a listener just like the addlistener function. The difference is the constructor accepts one more input, one object or a cell of objects, and the life cycle of the returned object will be linked also on these objects.Exemple:Without MagicListener:[Class1.m]classdef Class1 < handleeventsmyEventendend[Class2.m]classdef Class2 < handlemethodsfunction this = Class2( obj1 )addlistener( obj1, 'myEvent', @(H,E) this.callback() );endfunction callback( this )disp( 'CALLBACK!' );endendend>> obj1 = Class1();>> obj2 = Class2( obj1 );>> notify( obj1, 'myEvent' );CALLBACK!>> delete( obj2 );>> notify( obj1, 'myEvent' );Warning: Error occurred while executing callback:Invalid or deleted object.With MagicListener:[Class1.m]classdef Class1 < handleeventsmyEventendend[Class2.m]classdef Class2 < handlemethodsfunction this = Class2( obj1 )MagicListener( obj1, 'myEvent', @(H,E) this.callback(), this );endfunction callback( this )disp( 'CALLBACK!' );endendend>> obj1 = Class1();>> obj2 = Class2( obj1 );>> notify( obj1, 'myEvent' );CALLBACK!>> delete( obj2 );>> notify( obj1, 'myEvent' );
