LDicomContextGroup::GetFirst

#include "ltdic.h"

static pDICOMCONTEXTGROUP LDicomContextGroup::GetFirst()

Returns a pointer to the first Context Group in the Context Group Table.

Returns

Value Meaning
!NULL Pointer to a DICOMCONTEXTGROUP structure that specifies the first Context Group in the Context Group Table.
NULL The Context Group Table is empty.

Comments

Use the LDicomContextGroup::Load and LDicomContextGroup::Insert functions to add Context Groups to the Context Group Table.

Along with this function, the following functions can be used to maneuver through the Context Groups in the Context Group Table:

LDicomContextGroup::GetLast

LDicomContextGroup::GetNext

LDicomContextGroup::GetPrev

You can also use the LDicomContextGroup::GetCount and LDicomContextGroup::FindIndex functions to enumerate the Context Groups in the table.

The Coded Concepts of a Context Group can be investigated using the following functions:

LDicomContextGroup::GetFirstCodedConcept

LDicomContextGroup::GetLastCodedConcept

LDicomContextGroup::GetNextCodedConcept

LDicomContextGroup::GetPrevCodedConcept

LDicomContextGroup::GetCountCodedConcept

LDicomContextGroup::FindIndexCodedConcept
