35 * \brief Copy-on-write binary search table for structures that contain a key.
37 * This is a basic binary search table that employs a copy-on-write data
38 * storage mechanism. It can be used to contain a structure that has a key and
39 * possibly some data. The key should be a member of the element class and
40 * accessible with getKey(). A class containing the compare routine must be
46 #define BST_TEMPL_DECLARE class Element, class Key, \

70 * \fn SBstTable::insert(const Key &key, Element **lastFound)
71 * \brief Insert a new element with the given key.
73 * If the given key does not already exist in the table a new element is
74 * inserted with the given key. A constructor taking only const Key& is used
75 * to initialize the new element. If lastFound is given, it is set to the new
76 * element created. If the insert fails then lastFound is set to the existing
77 * element with the same key.
79 * \returns The new element created upon success, null upon failure.
83 * \fn SBstTable::insertMulti(const Key &key)
84 * \brief Insert a new element even if the key exists already.
86 * If the key exists already then the new element is placed next to some
87 * element with the same key. InsertMulti cannot fail. A constructor taking
88 * only const Key& is used to initialize the new element.
90 * \returns The new element created.
