/**
|
||||
* @brief An associative container which allows multiple entries of the same key.
|
||||
* @details
|
||||
* Same keys are ordered by KEY_COMPARE function which is std::less<key_t> > by default.
|
||||
*
|
||||
* It uses the ArrayList, so technically this is not a real map, it is an array of pairs
|
||||
* of type key_t, T. It is ordered by key_t as FixedMap but allows same keys. Thus it has a linear
|
||||
* complexity O(n). As long as the number of entries remains low, this
|
||||
* should not be an issue.
|
||||
* The number of insertion and deletion operation should be minimized
|
||||
* as those incur extensive memory move operations (the underlying container
|
||||
* is not node based).
|
||||
*
|
||||
* Its of fixed size so no allocations are performed after the construction.
|
||||
*
|
||||
* The maximum size is given as first parameter of the constructor.
|
||||
*
|
||||
* It provides an iterator to do list iterations.
|
||||
*
|
||||
* The type T must have a copy constructor if it is not trivial copy-able.
|
||||
*
|
||||
* @warning Iterators return a non-const key_t in the pair.
|
||||
* @warning A User is not allowed to change the key, otherwise the map is corrupted.
|
||||
