NAME

       Cache::Null - Null implementation of the Cache interface

SYNOPSIS

         use Cache::Null;

         my $cache = Cache::Null->new();

       See Cache for the usage synopsis.

DESCRIPTION

       The Cache::Null class implements the Cache interface, but does not actually persist data.
       This is useful when developing and debugging a system and you wish to easily turn off
       caching.  As a result, all calls return results indicating that there is no data stored.

CONSTRUCTOR

         my $cache = Cache::Null->new( %options )

       The constructor takes cache properties as named arguments, for example:

         my $cache = Cache::Null->new( default_expires => '600 sec' );

       See 'PROPERTIES' below and in the Cache documentation for a list of all available
       properties that can be set.  However it should be noted that all the existing properties,
       such as default_expires, have no effect in a Null cache.

METHODS

       See 'Cache' for the API documentation.
