Comments

If the IOD Structure is evaluated as a tree structure, this function returns the previous 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 IOD Structure is evaluated as a list, the previous 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.

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

• LDicomIOD::GetFirst
• LDicomIOD::GetLast
• 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
