Instance Method Details

#all_objects ⇒ Array<CodeObjects::Base>

Returns all the parsed objects in the registry, removing any objects that are not visible (private, protected) depending on the arguments passed to the command.

Returns:

  • (Array<CodeObjects::Base>) —

    all the parsed objects in the registry, removing any objects that are not visible (private, protected) depending on the arguments passed to the command.

#output(name, data, undoc = nil) ⇒ void

This method returns an undefined value.

Prints a statistic to standard out. This method is optimized for getting Integer values, though it allows any data to be printed.

Parameters:

  • name (String) —

    the statistic name

  • data (Integer, String) —

    the numeric (or any) data representing the statistic. If data is an Integer, it should represent the total objects of a type.

  • undoc (Integer, nil) (defaults to: nil) —

    number of undocumented objects for the type

Since:

  • 0.6.0

  @undocumented += undoc if undoc.is_a?(Integer)
  data =
    if undoc
      ("%5s (% 5d undocumented)" % [data, undoc])
    else
      "%5s" % data
    end
  log.puts("%-12s %s" % [name + ":", data])
end

#print_statistics ⇒ Object

Prints statistics for different object types

To add statistics for a specific type, add a method #stats_for_TYPE to this class that calls #output.
