Question
Can I use forward declarations with containers?
Answer
To control whether a forward declaration is generated when using a relation with * multiplicity, you must set the appropriate "IncludeDirective" property for your container and implementation type.
The "IncludeDirective" property (found under the :: metaclasses) specifies how container header files are included in generated files. The property is read through a pointer to the concrete relation.
The possible values are as follows:
strong - The #include directives are added to the header file.
weak - The #include directives are added to the source file with forward declarations in the header file.
For example, if you are using BoundedOrdered implementation with STL containers, set the STLContainers::BoundedOrdered::IncludeDirective property to "weak".
