LDicomIOD::GetLast

#include "Ltdic.h"

static pDICOMIOD LDicomIOD::GetLast(pIOD, bTree)

pDICOMIOD pIOD;	pointer to a DICOMIOD structure
L_BOOL bTree;	flag that indicates how to evaluate the IOD Structure

Returns a pointer to the last item in the IOD Structure.

Parameter	Description
pIOD	Pointer to a DICOMIOD structure within the IOD Structure. A pointer to the DICOMIOD structure that contains the last item in the IOD Structure will be returned.
bTree	Flag that indicates how the IOD Structure will be evaluated. Possible values are:
	Value	Meaning
	TRUE	Evaluate the IOD Structure as a tree.
	FALSE	Evaluate the IOD Structure as a list.

Returns

!NULL	A pointer to a DICOMIOD structure that contains the last item in the IOD Structure.
NULL	The IOD Structure is empty.

Comments

If the IOD Structure is evaluated as a tree structure, this function returns the last item on the same level as pIOD with the same parent as pIOD. Please note that the numbering of the items in this illustration is arbitrary and does not imply order.

If the passed pointer points to :	The function returns a pointer to :
Item 1	Item 2
Item 3	Item 4
Item 5	Item 5
Item 6	Item 7
NULL	Item 2

If the IOD Structure is evaluated as a list, the last item in the list is returned. Please note that the numbering of the items in this illustration does indicate the order of the items when the IOD Structure is evaluated as a list.

If the passed pointer points to :	The function returns a pointer to :
NULL	Item 30
Item 12	Item 30
Item 14	Item 30
Item 22	Item 30
Item 25	Item 30

The following functions will also help you navigate the IOD Structure as either a tree or a list:

LDicomIOD::GetFirst

LDicomIOD::GetPrev

LDicomIOD::GetNext

If you evaluate the IOD Structure as a tree, you can also use the following functions to navigate the tree:

LDicomIOD::GetRoot

LDicomIOD::GetParent

LDicomIOD::GetChild

Example

This example displays the name of the last item in the current level.

L_INT LDicomIOD_GetLastExample_1() 
{ 
   pDICOMIOD   pElement; 
   pDICOMIOD   pLast; 
   pElement = LDicomIOD::Find(NULL, TAG_PATIENT_NAME, IOD_TYPE_ELEMENT, FALSE); 
   if (pElement != NULL) 
   { 
      pLast = LDicomIOD::GetLast(pElement, TRUE); 
      ::MessageBox(NULL, pLast->pszName, TEXT("Notice"), MB_OK); 
   } 
   return DICOM_SUCCESS; 
} 
/* This example displays the name of the last item in the IOD table */ 
L_INT LDicomIOD_GetLastExample_2() 
{ 
   pDICOMIOD pLast; 
   pLast = LDicomIOD::GetLast(NULL, FALSE); 
   if (pLast != NULL) 
   { 
      ::MessageBox(NULL, pLast->pszName, TEXT("Notice"), MB_OK); 
   } 
   return DICOM_SUCCESS; 
}
