object to show.
This method produces an overview of the registry by printing a
header with information about the setup of the bitfield and a table with
one line for each flag in the bitfield. The table shows the start position
of each flag, the encoding type (see .determineEncoding), the
bitfield operator type and the columns that are tested by the flag.
