// File: NCollection_DefineDataMap.hxx
// Created: Thu Apr 24 15:02:53 2002

//
// Purpose: The DataMap is a Map to store keys with associated
// Items. See Map from NCollection for a discussion
// about the number of buckets.
//
// The DataMap can be seen as an extended array where
// the Keys are the indices. For this reason the
// operator () is defined on DataMap to fetch an Item
// from a Key. So the following syntax can be used :
//
// anItem = aMap(aKey);
// aMap(aKey) = anItem;
//
// This analogy has its limit. aMap(aKey) = anItem
// can be done only if aKey was previously bound to
// an item in the map.
