static pDICOMCODEDCONCEPT LDicomContextGroup::GetFirstCodedConcept(pContextGroup)
Returns a pointer to the first Coded Concept in the specified Context Group.
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.
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. |
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.
