Z RS( s Monitor object for downloads controlled by the Acquire class.
This is an mostly abstract class. You should subclass it and implement the
methods to get something useful.

Invoked when an item is confirmed to be up-to-date. For instance,
when an HTTP download is informed that the file on the server was
not modified.
N( ( R R ( ( s5 /usr/lib/python2.7/dist-packages/apt/progress/base.pyt ims_hit9 s c C s t S( s Prompt the user to change the inserted removable media.
The parameter 'media' decribes the name of the the media type that
should be changed, whereas the parameter 'drive' should be the
identifying name of the drive whose media should be changed.
This method should not return until the user has confirmed to the user
interface that the media change is complete. It must return True if
the user confirms the media change, or False to cancel it.

This method gets invoked while the Acquire progress given by the
parameter 'owner' is underway. It should display information about
the current state.
This function returns a boolean value indicating whether the
acquisition should be continued (True) or cancelled (False).

Base class for reporting the progress of adding a cdrom.
Can be used with apt_pkg.Cdrom to produce an utility like apt-cdrom. The
attribute 'total_steps' defines the total number of steps and can be used
in update() to display the current progress.
i c C s d S( s Ask for the name of the cdrom.
If a name has been provided, return it. Otherwise, return None to
cancel the operation.
N( ( R ( ( s5 /usr/lib/python2.7/dist-packages/apt/progress/base.pyt ask_cdrom_namet s c C s d S( s Ask for the CD-ROM to be changed.

operation.

The string 'text' defines the text which should be displayed. The

The parameter 'stage' is one of "upgrade", "install"
(both sent before unpacking), "configure", "trigproc", "remove",
"purge". This method is used for dpkg only.

This functions runs install actions. The parameter 'obj' may either
be a PackageManager object in which case its do_install() method is
called or the path to a deb file.
If the object is a PackageManager, the functions returns the result
of calling its do_install() method. Otherwise, the function returns
the exit status of dpkg. In both cases, 0 means that there were no
problems.
