static pDICOMIOD LDicomIOD::GetNext(pIOD, bTree)
Returns a pointer to the item in the IOD Structure that immediately follows the specified item.
Pointer to a DICOMIOD structure that contains an item in the IOD Structure. A pointer to the item in the IOD Structure that immediately follows this item will be returned.
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. |
Value | Meaning |
---|---|
!NULL | A pointer to a DICOMIOD structure that contains the item in the IOD Structure that immediately follows the item specified in pIOD. |
NULL | There is not an item following pIOD. (pIOD is the last item in the IOD Structure.) |
If the IOD Structure is evaluated as a tree structure, this function returns the next item on the same level as pIOD with the same parent as pIOD.
NOTE: 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 | NULL |
Item 6 | Item 7 |
If the IOD Structure is evaluated as a list, the next item in the list is returned.
NOTE: 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 |
---|---|
Item 14 | Item 15 |
Item 4 | Item 5 |
Item 8 | Item 9 |
Item 19 | Item 20 |
Item 27 | Item 28 |
Item 30 | NULL |
The following functions will also help you navigate the IOD Structure as either a tree or a list:
If you evaluate the IOD Structure as a tree, you can also use the following functions to navigate the tree:
