NAME

MyCPAN::Indexer::NullTester - Do nothing components

SYNOPSIS

Use this in backpan_indexer.pl by specifying it as the class you want to do nothing:

        # in backpan_indexer.config
        worker_class  MyCPAN::Indexer::NullTester

DESCRIPTION

This class implements all of the methods needed by all of the component classes. Thes methods don't do anything, so they can be useful to ignore parts of the system while you focus on developing another. For instance, you might use this module as the reporter_class, since it does nothing, which you work on the dispatcher_class.
