  • Method Details

    • containsValue

      public boolean containsValue​(boolean v)
      Description copied from interface: Float2BooleanMap
      Returns true if this map maps one or more keys to the specified value.
      Specified by:
      containsValue in interface Float2BooleanMap
      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 Float2BooleanMap
      Specified by:
      containsValue in interface java.util.Map<java.lang.Float,​java.lang.Boolean>

    • putAll

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

    • float2BooleanEntrySet

      public ObjectSet<Float2BooleanMap.Entry> float2BooleanEntrySet()
      Description copied from interface: Float2BooleanMap
      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:
      float2BooleanEntrySet in interface Float2BooleanMap
      Returns:
      a type-specific set view of the mappings contained in this map.
      See Also:
      Map.entrySet()

    • entrySet

      @Deprecated public ObjectSet<java.util.Map.Entry<java.lang.Float,​java.lang.Boolean>> 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 Float2BooleanMap
      Specified by:
      entrySet in interface java.util.Map<java.lang.Float,​java.lang.Boolean>
      Returns:
      a set view of the mappings contained in this map.
      See Also:
      Map.entrySet()

    • keySet

      public FloatSet keySet()
      Description copied from interface: Float2BooleanMap
      Specified by:
      keySet in interface Float2BooleanMap
      Specified by:
      keySet in interface java.util.Map<java.lang.Float,​java.lang.Boolean>
      Returns:
      a set view of the keys contained in this map.
      See Also:
      Map.keySet()

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