◆ IGESData_DefType

Some fields of an IGES entity may be.

Undefined
Defined as a positive integer
Defined as a reference to a specialized entity. A typical example of this kind of variation is color. This enumeration allows you to identify which of the above is the case. The semantics of the terms are as follows:
DefVoid indicates that the item contained in the field is undefined
DefValue indicates that the item is defined as an immediate positive integer value (i.e. not a pointer)
DefReference indicates that the item is defined as an entity
DefAny indicates the item could not be determined
ErrorVal indicates that the item is defined as an integer but its value is incorrect (it could be out of range, for example)
ErrorRef indicates that the item is defined as an entity but is not of the required type.
