Class Char2FloatAVLTreeMap

  • All Implemented Interfaces:
    Char2FloatFunction, Char2FloatMap, Char2FloatSortedMap, Function<java.lang.Character,​java.lang.Float>, java.io.Serializable, java.lang.Cloneable, java.util.function.Function<java.lang.Character,​java.lang.Float>, java.util.function.IntToDoubleFunction, java.util.Map<java.lang.Character,​java.lang.Float>, java.util.SortedMap<java.lang.Character,​java.lang.Float>

    public class Char2FloatAVLTreeMap
    extends AbstractChar2FloatSortedMap
    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.

      • addTo

        public float addTo​(char k,
                           float incr)
        Adds an increment to value currently associated with a key.

        Note that this method respects the default return value semantics: when called with a key that does not currently appears in the map, the key will be associated with the default return value plus the given increment.

        Parameters:
        k - the key.
        incr - the increment.
        Returns:
        the old value, or the default return value if no value was present for the given key.
      • clear

        public void clear()
        Description copied from interface: Char2FloatMap
        Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.

      • values

        public FloatCollection values()
        Returns a type-specific collection view of the values contained in this map.

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

      • clone

        public Char2FloatAVLTreeMap 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.
