getHighScalableIndex
long getHighScalableIndex()
Gets a number that is used by HighlyScalableMap. It could be an Object�s ID or hash code, for example. Be aware when using hash code, if two objects are
equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same result. Otherwise the
HighlyScalableMap will NOT work.
It�s recommended use the object�s ID.
In case of High Scalable Index changing, the element MUST be removed and after that added with the new High Scalable Index.
- Returns:
- The High Scalable Index
