If the passed object points to: | The method returns an object pointing to: |
---|---|
Item 1 | Item 2 |
Item 3 | Item 4 |
Item 5 | null |
Item 6 | Item 7 |
If the Data Set is evaluated as a list, the next item in the list is returned. 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 4 | Item 5 |
Item 8 | Item 9 |
Item 19 | Item 20 |
Item 27 | Item 28 |
Item 30 | null |
The following methods will also help you navigate the Data Set as either a tree or a list:
If you evaluate the Data Set as a tree, you can also use the following methods to navigate the tree:
A volatile element is an element that can be changed or destroyed in the process of inserting or setting an image. A non-volatile element is an element that must be changed manually. It is not changed or destroyed by inserting or setting an image.
For example, a grayscale image has elements DicomTag.SmallestImagePixelValue, DicomTag.LargestImagePixelValue, etc. If the image is changed to a color image, these elements disappear and the following elements appear: DicomTag.RedPaletteColorLookupTableDescriptor, etc. These are volatile elements since they are changed or destroyed when an image is changed or set.
To retrieve a next element that must be changed manually, i.e., is not volatile, set includeVolatile to false. To retrieve the first element, either volatile or non-volatile, set includeVolatile to true.
