Using Matlab 2021B version
I create a class which inherits both handel & matlab.mixin.indexing.RedefinesParen.
classdef Abc <handle & matlab.mixin.indexing.RedefinesParen
I create object arrays using this class.
I want to overload the parenthesis for the class so that it can perform special handling in addition to indexing into the object array ( normal operation ).
For example
Abc(‘special’) – performs special handling
Abc(2:3) – down selects only objects 2 to 3 (normal operation without RedefinesParen)
I have written the parenReference function as follows
function varargout = parenReference(obj,indexOp)
if isscalar(indexOp)
varargout{1} = obj(indexOp(1).Indices);
else
% Other special handling and forward indexing
%
end
end
The problem is that no matter how I try to select the subset of objects to return in the third line, it calls parenReference recusively and faults when recursion limit is reached. I have even tried
varargout{1} = builtin(‘subsref’,obj,substruct(‘()’,indexOp(1).Indices))
How do I select a subset of obj in this function without it being called recursively.
