L_BOOL LVectorObject::IsValid(L_VOID)
Determines whether the LVectorObject class object is valid.
Returns
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.
