    • singleton

      public static Short2FloatFunction singleton(short key, float value)
      Returns a type-specific immutable function containing only the specified pair. The returned function is serializable and cloneable.

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

      Parameters:
      key - the only key of the returned function.
      value - the only value of the returned function.
      Returns:
      a type-specific immutable function containing just the pair <key,value>.
    • singleton

      public static Short2FloatFunction singleton(Short key, Float value)
      Returns a type-specific immutable function containing only the specified pair. The returned function is serializable and cloneable.

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

      Parameters:
      key - the only key of the returned function.
      value - the only value of the returned function.
      Returns:
      a type-specific immutable function containing just the pair <key,value>.
    • synchronize

      public static Short2FloatFunction synchronize(Short2FloatFunction f)
      Returns a synchronized type-specific function backed by the given type-specific function.
      Parameters:
      f - the function to be wrapped in a synchronized function.
      Returns:
      a synchronized view of the specified function.

    • synchronize

      public static Short2FloatFunction synchronize(Short2FloatFunction f, Object sync)
      Returns a synchronized type-specific function backed by the given type-specific function, using an assigned object to synchronize.
      Parameters:
      f - the function to be wrapped in a synchronized function.
      sync - an object that will be used to synchronize the access to the function.
      Returns:
      a synchronized view of the specified function.

    • unmodifiable

      public static Short2FloatFunction unmodifiable(Short2FloatFunction f)
      Returns an unmodifiable type-specific function backed by the given type-specific function.
      Parameters:
      f - the function to be wrapped in an unmodifiable function.
      Returns:
      an unmodifiable view of the specified function.

    • primitive

      public static Short2FloatFunction primitive(Function<? super Short,? extends Float> f)
      Returns a (partial) type-specific function based on the given total generic function.

      The returned function contains all keys which are not mapped to null. If the function already is a primitive function, it is returned without changes.

      Warning: If the given function is a “widened” primitive function (e.g. an Int2IntFunction given to Short2ShortFunctions), it still is wrapped into a proxy, decreasing performance.

      Parameters:
      f - the function to be converted to a type-specific function.
      Returns:
      a primitive view of the specified function.
      Throws:
      NullPointerException - if f is null.
      Since:
