MATLAB Object-Oriented Programming

• Uses the displayPropertyGroups static method to generate the property display
  for valid objects.

Here is the implementation of displayNonScalarObjects:

methods (Access = protected)
function displayNonScalarObject(objAry)
dimStr = matlab.mixin.CustomDisplay.convertDimensionsToString(objAry);
cName = matlab.mixin.CustomDisplay.getClassNameForHeader(objAry);
headerStr = [dimStr,' ',cName,' members:'];
header = sprintf('%s\n',headerStr);
disp(header)
for ix = 1:length(objAry)
o = objAry(ix);
if ~isvalid(o)
str1 = matlab.mixin.CustomDisplay.getDeletedHandleText;
str2 = matlab.mixin.CustomDisplay.getClassNameForHeader(o);
headerInv = [str1,' ',str2];
tmpStr = [num2str(ix),'. ',headerInv];
numStr = sprintf('%s\n',tmpStr);
disp(numStr)
else
numStr = [num2str(ix),'. Employee:'];
disp(numStr)
propList = struct('Name',o.Name,...
'Department',o.Department);
propgrp = matlab.mixin.util.PropertyGroup(propList);
matlab.mixin.CustomDisplay.displayPropertyGroups(o,propgrp);
end
end
end
end

The displayEmptyObject Override

MATLAB calls the displayEmptyObject method to display empty object arrays. The
implementation of this method in the EmployeeInfo class builds a custom header for
empty objects following these steps:

• Gets the array dimensions in character format using the
  convertDimensionsToString static method.


• Gets text with the class name linked to the helpPopup function using the
  getClassNameForHeader static method.


• Builds and displays the custom text for empty arrays.

methods (Access = protected)
function displayEmptyObject(obj)
dimstr = matlab.mixin.CustomDisplay.convertDimensionsToString(obj);
className = matlab.mixin.CustomDisplay.getClassNameForHeader(obj);
