    • containsValue

      public boolean containsValue​(float v)
      Description copied from interface: Int2FloatMap
      Returns true if this map maps one or more keys to the specified value.
      Specified by:
      containsValue in interface Int2FloatMap
      See Also:
      Map.containsValue(Object)
    • getOrDefault

      @Deprecated public java.lang.Float getOrDefault​(java.lang.Object key, java.lang.Float defaultValue)
      Deprecated.
      Description copied from interface: Int2FloatMap
      Returns the value associated by this function to the specified key, or give the specified value if not present.

      This default implementation just delegates to the corresponding Map method.

      Specified by:
      getOrDefault in interface Function<java.lang.Integer,​java.lang.Float>
      Specified by:
      getOrDefault in interface Int2FloatFunction
      Specified by:
      getOrDefault in interface Int2FloatMap
      Specified by:
      getOrDefault in interface java.util.Map<java.lang.Integer,​java.lang.Float>
      Parameters:
      key - the key.
      defaultValue - the default value to return if not present.
      Returns:
      the corresponding value, or defaultValue if no value was present for the given key.

      Map.getOrDefault(Object, Object)
    • getOrDefault

      public float getOrDefault​(int key, float defaultValue)
      Description copied from interface: Int2FloatFunction
      Returns the value associated by this function to the specified key, or give the specified value if not present.
      Specified by:
      getOrDefault in interface Int2FloatFunction
      Specified by:
      getOrDefault in interface Int2FloatMap
      Overrides:
      getOrDefault in class Int2FloatFunctions.EmptyFunction
      Parameters:
      key - the key.
      defaultValue - the value to return if not present.
      Returns:
      the corresponding value, or defaultValue if no value was present for the given key.
      See Also:
      Function.getOrDefault(Object, Object)
    • containsValue

      @Deprecated public boolean containsValue​(java.lang.Object ov)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      containsValue in interface Int2FloatMap
      Specified by:
      containsValue in interface java.util.Map<java.lang.Integer,​java.lang.Float>
    • putAll

      public void putAll​(java.util.Map<? extends java.lang.Integer,​? extends java.lang.Float> m)
      Specified by:
      putAll in interface java.util.Map<java.lang.Integer,​java.lang.Float>
    • int2FloatEntrySet

      public ObjectSet<Int2FloatMap.Entry> int2FloatEntrySet()
      Description copied from interface: Int2FloatMap
      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:
      int2FloatEntrySet in interface Int2FloatMap
      Returns:
      a type-specific set view of the mappings contained in this map.
      See Also:
      Map.entrySet()
    • keySet

      public IntSet keySet()
      Description copied from interface: Int2FloatMap
      Specified by:
      keySet in interface Int2FloatMap
      Specified by:
      keySet in interface java.util.Map<java.lang.Integer,​java.lang.Float>
      Returns:
      a set view of the keys contained in this map.

      Map.keySet()
    • values

      public FloatCollection values()
      Description copied from interface: Int2FloatMap
      Specified by:
