The QTPlgDicomItemSequence class is a sequence of zero or more , where each item contains a set of . Instances of this class are used to setup the values of with a value representation of "SQ".
A Sequence of Items provides a flexible encoding scheme that may be used for simple structures of repeating sets of Data Elements, or the encoding of more complex Information Object Definitions often called folders. SQ Data Elements can also be used recursively to contain multi–level nested structures.
Items present in a "SQ" Data Element shall be an ordered set where each Item may be referenced by its ordinal position. Each Item shall be implicitly assigned an ordinal position starting with the value 1 for the first Item in the Sequence, and incremented by 1 with each subsequent Item. The last Item in the Sequence shall have an ordinal position equal to the number of Items in the Sequence.

The QTPlgDicomItemSequence class constructors are called when you create a new instance of the class, while the ˜QTPlgDicomItemSequence class destructor, is called automatically when the class is no more in use. Also, you can invoke the class destructor by setting the instance of the class to nil.
Once a new class instance is returned, it is good practice to check the class property to be sure that the new object can be used. See the validity requirements for more details.
The class provides you with the following initializer methods:
