| [MOFScript] undefined properties [message #377488] |

I have an input meta model for which one of the classes
has a property that does not required a value. Thus, I
want to make the generation of the output conditional
on whether or not a value is defined in the input model.
i.e something along the lines
if (self.p.oclIsDefined()) {
self.p.name
}
However, it appears that oclIsDefined is not among
the ocl functions defined in MOFScript. How is this
situation handled in MOFScript?
thanks
Andy.

Hi Andy,
I am not using MOFScript but in ATL you can use the function
oclIsUndefined().
Your code may look like (do not forget the "not") :
if (not self.p.oclIsUndefined()) {
self.p.name
)

Hello Andy,
I am not quite sure if I understand you correctly, but this might work
if (self.p != null) {
self.p.name
}
or try to print the property that does not have a value, and see what you
get,
or always use a defalult value in your model that you can check for.
