These template (GSAPI::IteratorElem, GSAPI::Element) and non-template (GSAPI::PrimElement) structures provide a common interface for the elements contained by the different containers and referenced by the different iterators.

template <typename ElemType>
struct GSAPI::IteratorElem {
    API_DatabaseInfo databaseInfo;
    ElemType         elem;
};

template <typename ElemType>
struct GSAPI::Element {
    API_ElemTypeID   elemType;
    UInt32           unId;
    ElemType         element;
    API_ElementMemo* memo;
};

struct GSAPI::PrimElement {
  API_PrimElement primElem;
    GSPtr         shapeProcParam1;
    GSPtr         shapeProcParam2;
    GSPtr         shapeProcParam3;
};

Description

The IteratorElem structure is as follows:

• an API_DatabaseInfo structure of the database which contains the element, and
• either an API_Attribute
• or an Element which in turn contains
  • the type, unique ID and possibly the API_ElementMemo of the API_Element it contains
  • the element which is either an API_Element
  • or a API_PrimElement of an API_Element which in turn contains
    • the API_PrimElement
    • and all the supplemental data returned by the ShapePrimsProc () for that primitive.
