Class TtlMap<K,​V>

  • All Implemented Interfaces:
    java.util.Map<K,​V>
    public final class TtlMap<K,​V>
extends TtlCollection<K>
implements java.util.Map<K,​V>
    This class implements the map interface to wrap some other instance of map, and maintains the entries into the map some time and then the elements are removed.
