  • Method Details

    • containsValue

      public boolean containsValue​(float v)
      Description copied from interface: Long2FloatMap
      Returns true if this map maps one or more keys to the specified value.
      Specified by:
      containsValue in interface Long2FloatMap
      See Also:
      Map.containsValue(Object)

    • containsValue

      @Deprecated public boolean containsValue​(java.lang.Object ov)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      containsValue in interface Long2FloatMap
      Specified by:
      containsValue in interface java.util.Map<java.lang.Long,​java.lang.Float>

    • putAll

      public void putAll​(java.util.Map<? extends java.lang.Long,​? extends java.lang.Float> m)
      Specified by:
      putAll in interface java.util.Map<java.lang.Long,​java.lang.Float>

    • long2FloatEntrySet

      public it.unimi.dsi.fastutil.objects.ObjectSet<Long2FloatMap.Entry> long2FloatEntrySet()
      Description copied from interface: Long2FloatMap
      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:
      long2FloatEntrySet in interface Long2FloatMap
      Returns:
      a type-specific set view of the mappings contained in this map.
      See Also:
      Map.entrySet()

    • entrySet

      @Deprecated public it.unimi.dsi.fastutil.objects.ObjectSet<java.util.Map.Entry<java.lang.Long,​java.lang.Float>> entrySet()
      Deprecated.
      Please use the corresponding type-specific method instead.
      Returns a set view of the mappings contained in this map.
      Specified by:
      entrySet in interface Long2FloatMap
      Specified by:
      entrySet in interface java.util.Map<java.lang.Long,​java.lang.Float>
      Returns:
      a set view of the mappings contained in this map.
      See Also:
      Map.entrySet()

    • keySet

      public it.unimi.dsi.fastutil.longs.LongSet keySet()
      Description copied from interface: Long2FloatMap
      Specified by:

      Specified by:
      keySet in interface java.util.Map<java.lang.Long,​java.lang.Float>
      Returns:
      a set view of the keys contained in this map.

      Specified by:
