Re: [Xotcl] Checking to see if a class is defined

Adam,

you can ask any XOTcl object (e.g. Object) if another identifier is the name of an object. e.g.:

% Object isobject MyClass 0

You can also ask any object whether it is a class:

% Class create MyClass ::MyClass % Object isobject MyClass 1 % MyClass isclass 1 %

an object would return 0 in this example:

% Object create m ::m % Object isobject m 1 %m isclass 0

see langRef for more details ...

I'm creating a test suite for an XOTcl class I'm writing, and I want to test this sequence:

(1) MyClass is undefined (initial state) --- package require MyClass succeeds (2) MyClass is defined (expected state after loading the package) (3) MyClass isa ::xotcl::Class (4) MyClass has methods x, y, z

However, I am not having any luck in testing #1 and #2. Is there any kind of introspection that can help me determine if a class is defined? Using [info exists MyClass] doesn't seem to work.

Thanks,
