# Cache::Null(3pm)

Null implementation of the Cache interface

## 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.
