  Parameters:
    `element` - the element to add.

### addAllOf

  Adds all elements of the specified list to the receiver.

  Specified by:
    `addAllOf` in interface `DoubleBufferConsumer`
  Parameters:
    `list` - the list of which all elements shall be added.

### clear

    public void clear()

  Sets the receiver's size to zero. In other words, forgets about any internally buffered elements.

### flush
