    • containsKey

      public boolean containsKey​(float key)
      Description copied from interface: Float2CharFunction
      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. In particular, this default implementation always returns true.

      Specified by:
      containsKey in interface Float2CharFunction
      Parameters:
      key - the key.
      Returns:
      true if this function associates a value to key.
      See Also:
      Function.containsKey(Object)
