#include "ltwrappr.h"

L_VOID LVectorEllipticalArc::LVectorEllipticalArc(pEllipticalArc =NULL)

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

pVECTORELLIPTICALARC pEllipticalArc;	/* pointer to a VECTORELLIPTICALARC structure */
pVECTOROBJECT pObject;	/* pointer to a VECTOROBJECT structure */
LVectorBase *pVector;	/* pointer to an LVectorBase object */

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

Parameter	Description
pEllipticalArc	Pointer to a VECTORELLIPTICALARC structure that contains information used to create and initialize the new vector elliptical arc object.
pObject	Pointer to a VECTOROBJECT structure that contains information used to create and initialize the new vector elliptical arc object.
pVector	Pointer to an LVectorBase object with which the newly constructed Vector Elliptical Arc object will be associated.

Returns

None

Comments

LVectorEllipticalArc::LVectorEllipticalArc(pEllipticalArc) is a constructor for the LVectorEllipticalArc object. It takes a valid pVECTORELLIPTICALARC pointer and creates an LVectorEllipticalArc object.

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

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