Enumeration Type Documentation

enum IGESData_DefType

• 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.
