      • _attrMap

        protected int[] _attrMap
        Int-based compact data structure that contains mapping from attribute names to attribute indexes in the main attribute name array.

        Data structure contains two separate areas; main hash area (with size _hashAreaSize), and remaining spillover area that follows hash area up until (but not including) _spillAreaEnd index. Main hash area only contains indexes (index+1; 0 signifying empty slot) to actual attributes; spillover area has both hash and index for any spilled entry. Spilled entries are simply stored in order added, and need to be searched using linear search. In case of both primary hash hits and spills, eventual comparison with the local name needs to be done with actual name array.

      • _hashAreaSize

        protected int _hashAreaSize
        Size of hash area in _attrMap; generally at least 20% more than number of attributes (_attrCount).

      • _spillAreaEnd

        protected int _spillAreaEnd
        Pointer to int slot right after last spill entry, in _attrMap array.
