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.
