/**
|
|
* 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.
