static pDICOMCONTEXTGROUP LDicomContextGroup::GetFirst()
Returns a pointer to the first Context Group in the Context Group Table.
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. |
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:
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
