Public Function FindNextElement( _ByVal element As Leadtools.Dicom.DicomElement, _ByVal tree As Boolean _) As Leadtools.Dicom.DicomElement
public Leadtools.Dicom.DicomElement FindNextElement(Leadtools.Dicom.DicomElement element,bool tree)
public DicomElement findNextElement(DicomElement element, boolean tree) function Leadtools.Dicom.DicomDataSet.FindNextElement(element ,tree)
public:Leadtools.Dicom.DicomElement^ FindNextElement(Leadtools.Dicom.DicomElement^ element,bool tree)
Parameters
element
An item in the Data Set.
tree
true to evaluate the Data Set as a tree; false to evaluate the Data Set as a list.
Return Value
The next item in the Data Set with a specific Tag, or a null reference (Nothing in VB) if an item with the specified Tag was not found.
Remarks
Note: This method does not specify a Tag to use when searching. However the tag that was used in the last call to FindFirstElement or FindLastElement is used by default when searching. For the sake of the following illustrations, the order of siblings is top to bottom.
If the Data Set is evaluated as a tree structure, this method returns the next item on the same level as element with the same parent as element, that has Tag tag.
Please note that the numbering of the items of interest in this first illustration is arbitrary and does not imply order.
| If the passed object points to: | The method returns an object pointing to: |
|---|---|
| Item 1 | The next sibling (same level, same parent) of Item 1 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. |
| Item 2 | The next sibling (same level, same parent) of Item 2 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. |
| Item 3 | The next sibling (same level, same parent) of Item 3 that has Tag tag, if such an item exists. If such an item does not exist, the method returns null. |
If the Data Set is evaluated as a list, this method returns the next item in the entire list that has tag tag.
Please note that the numbering of the items in the following illustration does indicate the order of the items when the Data Set is evaluated as a list.
| If the passed object points to: | The method returns an object pointing to: |
|---|---|
| Item 1 | The next item in the list that has Tag tag, if such an item exists. If an item with Tag tag is not found, null is returned. |
| Item 14 | The next item in the list that has Tag tag, if such an item exists. If an item with Tag tag is not found, null is returned. |
| Item 22 | The next item in the list that has Tag tag, if such an item exists. If an item with Tag tag is not found, null is returned. |
