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.
