    • containsValue

      public boolean containsValue​(java.lang.Object v)
      Specified by:
      containsValue in interface java.util.Map<java.lang.Byte,​V>
    • putAll

      public void putAll​(java.util.Map<? extends java.lang.Byte,​? extends V> m)
      Specified by:
      putAll in interface java.util.Map<java.lang.Byte,​V>
    • byte2ReferenceEntrySet

      public ObjectSet<Byte2ReferenceMap.Entry<V>> byte2ReferenceEntrySet()
      Description copied from interface: Byte2ReferenceMap
      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:
      byte2ReferenceEntrySet in interface Byte2ReferenceMap<V>
      Returns:
      a type-specific set view of the mappings contained in this map.

      @Deprecated public ObjectSet<java.util.Map.Entry<java.lang.Byte,​V>> entrySet()
      Deprecated.
      Please use the corresponding type-specific method instead.
      Returns a set view of the mappings contained in this map.
