stop creation

[Frank]

Hello,
I have as class and when I get wrong data when creating the object (in the
'new' routine) I want to break off the creation of the classObject, so it
results in 'nothing' to the creator . How can I do that?
Thanx
Frank

Catch the error in the procedure creating the object.
Optionally/Additionally add a shared function to the class creating the
object and returning Nothing if an exception was thrown.

Throw an exception in the ctor. Alternatively, you can provide a shared
method that returns an object of the class' type or 'Nothing' if
creation fails.
