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.

SEE ALSO ^
