Primitive Types reused in UML [message #476941] Sat, 16 February 2008 22:18 Go to next message

Hi,

I imported UMLResource.UML_PRIMITIVE_TYPES_LIBRARY_URI and tried to get
"int". It gave a null pointer. The "int" is declared als "Integer" in
it. There are only four primitive types "Integer", "Boolean", "String"
and "Unlimited". How about others like "Double" or "Char"? I also need a
"byte" of Java.

Any solutions are welcome!

Zengyu

Hi,
You should use the JAVA_PRIMITIVE_TYPES_LIBRARY_URI that is also declared
in UMLResource. It contains all Java primitives, but will have 'double'
instead of Double, as the latter is not a primitive type in Java.

The UML built-in primitive types defined in the UML spec are very limited
(as you observed). It is expected that other libraries are used, depending
on your purpose and platform.

Regards,
Dave Carlson
