LDicomContextGroup::GetFirstCodedConcept

#include "ltdic.h"

static pDICOMCODEDCONCEPT LDicomContextGroup::GetFirstCodedConcept(pContextGroup)

Returns a pointer to the first Coded Concept in the specified Context Group.

Parameters

pDICOMCONTEXTGROUP pContextGroup

Pointer to a DICOMCONTEXTGROUP structure that specifies a Context Group in the Context Group Table. The function Returns a pointer to the first Coded Concept in this Group, if it contains any.

Returns

Value Meaning
!NULL Pointer to a DICOMCODEDCONCEPT structure that specifies the first Coded Concept in the specified Context Group.
NULL The specified Context Group does not contain any Coded Concepts.

Comments

Along with this function, the following functions can be used to maneuver through the Coded Concepts of a Context Group in the Context Group Table:

LDicomContextGroup::GetLastCodedConcept

LDicomContextGroup::GetNextCodedConcept

LDicomContextGroup::GetPrevCodedConcept

You can also use the LDicomContextGroup::GetCountCodedConcept and LDicomContextGroup::FindIndexCodedConcept functions to enumerate the Coded Concepts.

Use the LDicomContextGroup::GetContextGroup function to obtain the Context Group to which a Coded Concept belongs.
