Class MinimumMemoryMap<K,​V>

  • All Implemented Interfaces:
    java.util.Map<K,​V>

    public class MinimumMemoryMap<K,​V>
    extends java.lang.Object
    implements java.util.Map<K,​V>
    Array based implementation of the Map interface. This implementation uses the minimum amount of memory to store keys and values. Keys are kept in sorted order, so time for inserts and lookups is O(log2(N)).
