  • Method Details

    • comparator

      public FloatComparator comparator()
      Description copied from interface: Float2DoubleSortedMap
      Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.
      Specified by:
      comparator in interface Float2DoubleSortedMap
      Specified by:
      comparator in interface java.util.SortedMap<java.lang.Float,​java.lang.Double>
      See Also:
      SortedMap.comparator()

    • float2DoubleEntrySet

      public ObjectSortedSet<Float2DoubleMap.Entry> float2DoubleEntrySet()
      Description copied from interface: Float2DoubleMap
      Returns a type-specific set view of the mappings contained in this map.

      This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

      Specified by:
      float2DoubleEntrySet in interface Float2DoubleMap
      Specified by:
      float2DoubleEntrySet in interface Float2DoubleSortedMap
      Overrides:
      float2DoubleEntrySet in class Float2DoubleMaps.EmptyMap
      Returns:
      a type-specific set view of the mappings contained in this map.
      See Also:
      Map.entrySet()

    • entrySet

      @Deprecated public ObjectSortedSet<java.util.Map.Entry<java.lang.Float,​java.lang.Double>> entrySet()
      Deprecated.
      Please use the corresponding type-specific method instead.
      Returns a sorted-set view of the mappings contained in this map.
      Specified by:
      entrySet in interface Float2DoubleMap
      Specified by:
      entrySet in interface Float2DoubleSortedMap
      Specified by:

      Specified by:
      entrySet in interface java.util.SortedMap<java.lang.Float,​java.lang.Double>
      Returns:
      a sorted-set view of the mappings contained in this map.
