    • containsKey

      public boolean containsKey(Object key)
      Description copied from interface: Function
      Returns true if this function contains a mapping for the specified key.

      Note that for some kind of functions (e.g., hashes) this method will always return true. This default implementation, in particular, always return true.

      Specified by:
      containsKey in interface Function<K,Byte>
      Parameters:
      key - the key.
      Returns:
      true if this function associates a value to key.

      getByte in interface Object2ByteFunction<K>
      Parameters:
      key - the key.
      Returns:
      the corresponding value, or the default return value if no value was present for the given key.
