LVectorStock::LVectorStock(pStock = NULL)

LVectorStock::LVectorStock(pObject, pVector =NULL)

Constructs and initializes the different member variables of the LVectorStock object.



Pointer to a VECTORSTOCK structure that contains information used to create and initialize the new vector stock object.


Pointer to a VECTOROBJECT structure that contains information used to create and initialize the new vector stock object.

LVectorBase *pVector

Pointer to an LVectorBase object with which the newly constructed vector stock object will be associated.




LVectorStock::LVectorStock(pStock) is a constructor for the LVectorStock object. It takes a valid pVECTORSTOCKpointer and creates an LVectorStock object.

LVectorStock::LVectorStock(pObject, pVector=NULL) creates an LVectorStock object based on the information provided in pObject and associates the newly created LVectorStock object with the specified LVectorBase object. This constructor can be used with the LVectorLayer::EnumObjects function, which returns a valid pVECTOROBJECT pointer in the LVectorLayer::EnumObjectsCallBack member function. It can also be used with LVectorBase::VectorEventProcCallBack, which can also return a pObject.

Note that it is possible to construct an invalid LVectorStock object using the LVectorStock::LVectorStock(pObject, pVector=NULL) constructor. For example:

   //pObject->nType == type other than VECTOR_STOCK   
   //LVectorBase *pVector is valid   
   LVectorStock MyVectorStock(pObject, pVectorBase);   
   if (MyVectorStock.IsTypeValid() == FALSE)   
      MessageBox(NULL, TEXT("Invalid Vector Object"), TEXT(""), MB_OK);
