38 * \ref DocEntrySet is an abstract base class for \ref ElementSet
39 * and \ref SQItem which are both containers for DocEntries.
40 * \ref ElementSet is based on the STL map<> container
41 * (see \ref ElementSet::TagHT), as opposed to \ref SQItem
42 * which is based on an STL list container (see \ref ListDocEntry).
43 * Since the syntax for adding a new element to a map<> or a list<>
44 * differ, \ref DocEntrySet is designed as an adapter to unify the
45 * interfaces of \ref DocEntrySet and \ref ElementSet.
46 * As an illustration of this design, please refer to the implementation
47 * of \ref AddEntry (or any pure virtual method) in both derived classes.
48 * This adapter unification of interfaces enables the parsing of a
49 * DICOM header containing (optionaly heavily nested) sequences to be
50 * written recursively [see \ref Document::ParseDES
51 * which calls \ref Document::ParseSQ, which in turns calls
52 * \ref Document::ParseDES ].
54 * \note Developpers should strongly resist to the temptation of adding
55 * members to this class since this class is designed as an adapter
56 * in the form of an abstract base class.
