Class Long2ObjectAVLTreeMap<V>

  • All Implemented Interfaces:
    Function<java.lang.Long,​V>, Long2ObjectFunction<V>, Long2ObjectMap<V>, Long2ObjectSortedMap<V>, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<java.lang.Long,​V>, java.util.function.LongFunction<V>, java.util.Map<java.lang.Long,​V>, java.util.SortedMap<java.lang.Long,​V>

    public class Long2ObjectAVLTreeMap<V>
    extends AbstractLong2ObjectSortedMap<V>
    implements java.io.Serializable, java.lang.Cloneable
    A type-specific AVL tree map with a fast, small-footprint implementation.

    The iterators provided by the views of this class are type-specific bidirectional iterators. Moreover, the iterator returned by iterator() can be safely cast to a type-specific list iterator.

      • clear

        public void clear()
        Description copied from interface: Long2ObjectMap
        Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.
        Specified by:
        clear in interface Function<java.lang.Long,​V>
        Specified by:
        clear in interface Long2ObjectMap<V>

        Map.clear()
      • size

        public int size()
        Description copied from interface: Long2ObjectMap
        Returns the number of key/value mappings in this map. If the map contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.
        Specified by:
        size in interface Function<java.lang.Long,​V>
        Specified by:
        size in interface Long2ObjectMap<V>

      • isEmpty

        public boolean isEmpty()
        Specified by:
        isEmpty in interface java.util.Map<java.lang.Long,​V>

      • keySet

        public LongSortedSet keySet()
        Returns a type-specific sorted set view of the keys contained in this map.

        In addition to the semantics of Map.keySet(), you can safely cast the set returned by this call to a type-specific sorted set interface.

      • values

        public ObjectCollection<V> values()
        Returns a type-specific collection view of the values contained in this map.

        Returns:
        a type-specific collection view of the values contained in this map.

      • comparator

        public LongComparator comparator()
        Description copied from interface: Long2ObjectSortedMap
        Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

        Description copied from interface: Long2ObjectSortedMap
        Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

        SortedMap.subMap(Object,Object)
      • clone

        public Long2ObjectAVLTreeMap<V> clone()
        Returns a deep copy of this tree map.

        This method performs a deep copy of this tree map; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.

        Returns:
        a deep copy of this tree map.
