LVectorChord::LVectorChord

#include "ltwrappr.h"

L_VOID LVectorChord::LVectorChord(pChord = NULL)

L_VOID LVectorChord::LVectorChord(pObject, pVector =NULL)

pVECTORCHORD pChord;	/* pointer to a VECTORPIE/VECTORCHORD structure */
pVECTOROBJECT pObject;	/* pointer to a VECTOROBJECT structure */
LVectorBase *pVector;	/* pointer to an LVectorBase object */

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

Parameter	Description
pChord	Pointer to a VECTORCHORD structure that contains information used to create and initialize the new vector chord object.
pObject	Pointer to a VECTOROBJECT structure that contains information used to create and initialize the new vector chord object.
pVector	Pointer to an LVectorBase object with which the newly constructed vector chord object will be associated.

Returns

None

Comments

LVectorChord::LVectorChord(pChord) is a constructor for the LVectorChord object. It takes a valid pVECTORCHORD pointer and creates an LVectorChord object.

LVectorChord::LVectorChord(pObject, pVector=NULL) creates an LVectorChord object based on the information provided in pObject and associates the newly created LVectorChord 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 LVectorChord object using the LVectorChord::LVectorChord(pObject, pVector=NULL) constructor. For example:

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