Direct Known Subclasses:

DictionaryItemList

public class DataItemList

extends java.lang.Object

Stores and manages the list of Data Items defined in a cif dictionary.
There may be multiple null objects in the ArrayList, which are stored with a null DataItem index; e.g. when a data file loop is read that contains multiple unwanted value fields. The HashMap will only keep a pointer (Integer) to the last one stored; but since the elementAt() method will return null for all the indicies stored with null values this doesn't matter.
