LVectorBase::EnumGroupsCallBack

#include "ltwrappr.h"

virtual L_INT LVectorBase::EnumGroupsCallBack(pVector, pGroup)

Processes each vector group enumerated by the LVectorBase::EnumGroups function.

Parameters

pVECTORHANDLE pVector

Pointer to the vector handle that contains the groups to enumerate.

pVECTORGROUP pGroup

Pointer to the vector group being processed.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

The LVectorBase::EnumGroups function calls the callback function as it gets a pointer to each vector group.

To use LVectorBase::EnumGroupsCallBack, derive a class from LVectorBase and override the EnumGroupsCallBack member function. Note that this callback function does not return an LVectorGroupobject.

To get detailed information about each enumerated group, attach pGroup to an LVectorGroup class object and call LVectorGroup::GetGroupDesc.
