Detailed Description

template<class TheKeyType, class TheItemType, class Hasher = NCollection_DefaultHasher<TheKeyType>>
class NCollection_IndexedDataMap< TheKeyType, TheItemType, Hasher >

Purpose: An indexed map is used to store keys and to bind an index to them. Each new key stored in the map gets an index. Index are incremented as keys are stored in the map. A key can be found by the index and an index by the key. No key but the last can be removed so the indices are in the range 1.. Extent. An Item is stored with each key.

This class is similar to IndexedMap from NCollection with the Item as a new feature. Note the important difference on the operator (). In the IndexedMap this operator returns the Key. In the IndexedDataMap this operator returns the Item.

See the class Map from NCollection for a discussion about the number of buckets.
