NAME

       Mail::SpamAssassin::Util::Progress - Progress bar support for SpamAssassin

SYNOPSIS

	 my $progress = Mail::SpamAssassin::Util::Progress->new({total => 100});

	 $msgcount = 0;

	   # do something here
	   $msgcount++;
	   $progress->update($msgcount);
	 }

	 $progress->final();

DESCRIPTION

       This module implements a progress bar for use in SpamAssassin scripts and modules.  It allows you to create the progress bar, update it and
       print out the final results of a particular run.

   new
       public class (Mail::SpamAssassin::Util::Progress) new (\% $args)

       Description: Creates a new Mail::SpamAssassin::Util::Progress object, valid values for the $args hashref are:

       total (required)
	   The total number of messages expected to be processed.  This item is required.

       fh [optional]
	   An optional filehandle may be passed in, otherwise STDERR will be used by default.

       term [optional]
	   The module will attempt to determine if a valid terminal exists on the STDIN filehandle.  This item allows you to override that value.

   init_bar
       public instance () init_bar()

       Description: This method creates the initial progress bar and is called automatically from new.	In addition you can call init_bar on an
       existing object to reset the bar to it's original state.

   update
       public instance () update ([Integer $num_done])

       Description: This method is what gets called to update the progress bar.  You may optionally pass in an integer value that indicates how
       many messages have been processed.  If you do not pass anything in then the num_done value will be incremented by one.

   final
       public instance () final ([Integer $num_done])

       Description: This method should be called once all processing has finished.  It will print out the final msgs per sec calculation and the
       total time taken.  You can optionally pass in a num_done value, otherwise it will use the value calculated from the last call to update.
