    • EMPTY_MAP

      public static final Float2CharMaps.EmptyMap EMPTY_MAP
      An empty type-specific map (immutable). It is serializable and cloneable.

    • fastIterator

      public static ObjectIterator<Float2CharMap.Entry> fastIterator(Float2CharMap map)
      Returns an iterator that will be fast, if possible, on the entry set of the provided map.
      Parameters:
      map - a map from which we will try to extract a (fast) iterator on the entry set.
      Returns:
      an iterator on the entry set of the given map that will be fast, if possible.
      Since:
      8.0.0
    • fastForEach

      public static void fastForEach(Float2CharMap map, Consumer<? super Float2CharMap.Entry> consumer)
      Iterates quickly, if possible, on the entry set of the provided map.
      Parameters:
      map - a map on which we will try to iterate quickly.
      consumer - the consumer that will be passed to Float2CharMap.FastEntrySet.fastForEach(Consumer), if possible, or to Iterable.forEach(Consumer).
      Since:
      8.1.0
    • fastIterable

      public static ObjectIterable<Float2CharMap.Entry> fastIterable(Float2CharMap map)
      Returns an iterable yielding an iterator that will be fast, if possible, on the entry set of the provided map.
      Parameters:
      map - a map from which we will try to extract an iterable yielding a (fast) iterator on the entry set.
      Returns:
      an iterable yielding an iterator on the entry set of the given map that will be fast, if possible.
      Since:
      8.0.0
    • singleton

      public static Float2CharMap singleton(float key, char value)
      Returns a type-specific immutable map containing only the specified pair. The returned map is serializable and cloneable.

      Note that albeit the returned map is immutable, its default return value may be changed.

      Parameters:
      key - the only key of the returned map.
      value - the only value of the returned map.
      Returns:
      a type-specific immutable map containing just the pair &lt;key,value&gt;.
    • singleton

      public static Float2CharMap singleton(Float key, Character value)
      Returns a type-specific immutable map containing only the specified pair. The returned map is serializable and cloneable.

      Note that albeit the returned map is immutable, its default return value may be changed.

      Parameters:
      key - the only key of the returned map.
      value - the only value of the returned map.
      Returns:
      a type-specific immutable map containing just the pair &lt;key,value&gt;.
    • synchronize

      public static Float2CharMap synchronize(Float2CharMap m)
      Returns a synchronized type-specific map backed by the given type-specific map.
      Parameters:
      m - the map to be wrapped in a synchronized map.
      Returns:
      a synchronized view of the specified map.

    • synchronize

      public static Float2CharMap synchronize(Float2CharMap m, Object sync)
      Returns a synchronized type-specific map backed by the given type-specific map, using an assigned object to synchronize.
      Parameters:
      m - the map to be wrapped in a synchronized map.
      sync - an object that will be used to synchronize the access to the map.
      Returns:
      a synchronized view of the specified map.

    • unmodifiable

      public static Float2CharMap unmodifiable(Float2CharMap m)
      Returns an unmodifiable type-specific map backed by the given type-specific map.
      Parameters:
      m - the map to be wrapped in an unmodifiable map.
      Returns:
      an unmodifiable view of the specified map.
