I understand that you want to know how to access fields within a nested structure. It appears that you have implemented the "ischild" function to validate the existence of a field within an object.
You can follow the below workaround to resolve the issue.
- Create two classes, namely “inner” and “outer” where “outer” has the property that holds an object of the “inner” class.
classdef outer
properties
innerObj
end
methods
function obj = outer(field, value)
obj.innerObj = inner(field, value);
end
function innerObjPropFromOuterObj(obj)
disp(['obj.innerObj.innerProp.field', obj.innerObj.innerProp.field]) % target value
end
end
end
classdef inner
properties
innerProp
end
methods
function obj = inner(field, value)
obj.innerProp = struct(field, value);
end
end
end
2. create an object of "outer" class.
obj = outer("field","value");
Additionally, your implementation and workflow involving the “ischild”, “getfield” and “setfield” functions also appear to be correct.
I hope this helps.
