Definition of empty non-polymorphic structs. #83

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Franca allows definition of unions with no elements. When serializing such a 
union the union index is undefined.

A similiar problem with empty structs. DBus is not able to serialize structs 
with an undefined signature.

Empty unions will be disallowed starting from 0.9.0, see issue 70, V1.

Polymorphic empty structs will not be forbidden, I guess there could be use 
cases where an empty polymorphic struct is used as root for an inheritance 
tree. This won't be a problem for the plain D-Bus transformation as well (it 
creates a "iv" from polymorphic structs). 

However, maybe we should disallow empty non-polymorphic structs. Thinking about 
this...

We will disallow empty non-polymorphic structs by validation.

Changed title from union to struct.
