Matlab static variable that can be modified by super class and sub class?
显示 更早的评论
I have following structure where I have a superclass and two subclasses
classdef A
properties
staticvar
end
end
And two subclasses of A
classdef B < A
properties
end
end
classdef C < A
properties
end
end
Is there a way I can use "staticvar" such that the "staticvar" value can be modified by any of the classes and its value is reflected when accessed by any of the class?

You mean you want all instances of the class and its subclasses to share the same copy of staticvar? If so, you can write the superclass like this.
classdef A
properties(Dependent)
staticvar
end
methods
function val=get.staticvar(~)
val=manage_staticVar;
end
function obj=set.staticvar(obj,val)
manage_staticVar(val);
end
end
end
function out=manage_staticVar(val) %Not a class method - can be class-related function
persistent p
if nargin, p=val; end
out=p;
end
