//! This class defines a list of Entities (Transient Objects),
|
|
//! it can be used as a field of other Transient classes, with
|
|
//! these features :
|
|
//! - oriented to define a little list, that is, slower than an
|
|
//! Array or a Map of Entities for a big count (about 100 and
|
|
//! over), but faster than a Sequence
|
|
//! - allows to work as a Sequence, limited to Clear, Append,
|
|
//! Remove, Access to an Item identified by its rank in the list
|
|
//! - space saving, compared to a Sequence, especially for little
|
|
//! amounts; better than an Array for a very little amount (less
|
|
//! than 10) but less good for a greater amount
|
|
//!
|
|
//! Works in conjunction with EntityCluster
|
|
//! An EntityList gives access to a list of Entity Clusters, which
|
|
//! are chained (in one sense : Single List)
|
|
//! Remark : a new Item may not be Null, because this is the
|
|
//! criterium used for "End of List"
