Comments

LVectorGroup::LVectorGroup(pGroup, pVector=NULL) is a constructor for the LVectorGroup object. It takes a valid pVECTORGROUP pointer and creates an LVectorGroup object. This constructor should mainly be used with the LVectorBase::EnumGroups function, which returns a valid pVECTORGROUP pointer in its LVectorBase::EnumGroupsCallBack member function.

LVectorGroup::LVectorGroup(pVector) creates a valid LVectorGroup object that is associated with the specified LVectorBase object.

LVectorGroup::LVectorGroup(pGroupDesc=NULL, pVector=NULL) creates an LVectorGroup object based on the information provided in pGroupDesc and associates the newly created LVectorGroup object with the specified LVectorBase object.

To use the LVectorGroup::LVectorGroup(pGroupDesc=NULL, pVector=NULL) constructor, optionally declare a variable of type VECTORGROUPDESC, fill the structure and pass its address to this constructor. To associate the newly created vector group with an LVectorBase object, pass a valid pointer to an LVectorBase object as the second parameter. If the second parameter is NULL, then the LVectorGroup object is not yet associated with an LVectorBase object. The following functions automatically associate an LVectorGroup object with an LVectorBase object: LVectorBase::AddGroup, LVectorBase::GetGroupByName and LVectorBase::GetGroupByIndex. The LVectorGroup::SetVector also associates an LVectorGroup object with an LVectorBase object.
