Definition Table Specification and Usage

The definition table module embodies the concept of a set of distinguishable entities, each having some set of properties.

Typical Specification (.pdl file)

    Name: Type;

generates the basic query operations:

   GetName(DefTableKey key, Type deflt)
   void SetName(DefTableKey key, Type add, Type replace)
   void ResetName(DefTableKey key, Type val)

Typical Error Situations

  • Accessing a property before it has been set:

    ==> wrong runtime behavior

    Typical Solution Pattern:

        RULE r_root: ... 
                   root.propset = CONSTITUENTS objects.propset;
        RULE r_set: ...
                   x.propset = SetProp(xyz_key, v1, v2);
        RULE r_get: ...
                   ... y.GetProp(y_key, defltval) 
                                <- INCLUDING root.propset;
