Summary

Returns a pointer to the Context Group in the Context Group Table that has the specified Context Identifier (CID).

Syntax

#include "ltdic.h"

static pDICOMCONTEXTGROUP LDicomContextGroup::Find(pszContextID)

Parameters

L_TCHAR * pszContextID

Character string that contains a Context Identifier (CID). For a list of the Context Identifiers of the Context Groups maintained internally, refer to Context Identifier Values. The function Returns a pointer to the DICOMCONTEXTGROUP structure that specifies the Context Group in the Context Group Table for the specified Context ID.

Returns

Value	Meaning
!NULL	Pointer to a DICOMCONTEXTGROUP structure that specifies the Context Group in the Context Group Table for the specified Context ID.
NULL	None of the Context Groups in the Context Group Table has the specified Context ID.

Comments

A Context Group is identified by its Context Identifier (CID). For a list of the Context Identifiers of the Context Groups maintained internally, refer to Context Identifier Values.

NOTE: Only the Context Groups in the Context Group Table are searched by the function. To add Context Groups to the table, call the LDicomContextGroup::Load and LDicomContextGroup::Insert functions.

To search for a specific Coded Concept in a Context Group, call the LDicomContextGroup::FindCodedConcept function.
