checkClass inspects the specified Java, Matlab (MCOS), .NET, Python, C++ (CLib), or COM (ActiveX) object reference or class-name, and reports its superclass(es), interfaces, new/modified methods, super/sub-classes, properties, events, constants, enumerations and annotations.
metadata = checkClass(...) returns a meta.class or meta.package object that encapsulates the input object.
This utility complements the GUI-based UIINSPECT utility by being Command-Prompt based and also by highlighting the object components that were modified in the inspected class compared to its parent superclass.
Syntax:
checkClass(objectReference)
checkClass(className)
checkClass(..., level) % default level=1 % Note: changed default in v1.32!
metadata = checkClass(...)
Usage examples:
% Java objects/classes
checkClass('java.lang.String')
checkClass(javax.swing.JButton)
jButton = javax.swing.JButton('Click me!');
jButton.checkClass; % or: checkClass(jButton)
checkClass(com.mathworks.mwswing.MJToolBar)
checkClass(com.mathworks.mde.desk.MLDesktop.getInstance)
% Matlab (MCOS) objects/classes/packages
checkClass(gcf)
checkClass('matlab.ui.Figure')
checkClass matlab.ui.Figure % equivalent to above
checkClass matlab.ui.control % package name (contains classes, sub-packages)
% .NET objects/classes/packages
checkClass('NET.Assembly')
checkClass(System.Diagnostics.Process.GetCurrentProcess)
% Python objects/classes/modules
checkClass('py.inspect')
checkClass(py.importlib.import_module('calendar'))
