#include "ltwrappr.h"

L_BOOL LVectorObject::IsValid(L_VOID)

Determines whether the LVectorObject class object is valid.

Value	Meaning
TRUE	The LVectorObject class object is valid.
FALSE	The LVectorObject class object is not valid.

Comments

An LVectorObject is invalid if it is created using the LVectorObject::LVectorObject() constructor. It remains invalid until it is added to a vector layer, using LVectorLayer::AddObject, or it is passed to LVectorBase::HitTest.

A valid LVectorObject object will become invalid when it is exploded, using LVectorObject::ExplodeObject.
