LVectorSpline::LVectorSpline

#include "ltwrappr.h"

LVectorSpline:: LVectorSpline (pSpline = NULL)

LVectorSpline:: LVectorSpline (pObject, pVector =NULL)

pVECTORSPLINE pSpline;	pointer to a VECTORSPLINE structure
pVECTOROBJECT pObject;	pointer to a VECTOROBJECT structure
LVectorBase *pVector;	pointer to an LVectorBase object

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

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

Returns

None.

Comments

LVectorSpline::LVectorSpline(pSpline) is a constructor for the LVectorSpline object. It takes a valid pVECTORSPLINE pointer and creates an LVectorSpline object.

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

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