=head1 NAME

Cache::NullCache -- implements the Cache interface.

=head1 DESCRIPTION

The NullCache class implements the Cache::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 to get and get_object will return undef.

=head1 SYNOPSIS

use Cache::NullCache;

my $cache = new Cache::NullCache( );

See Cache::Cache for the usage synopsis.

=head1 METHODS

See Cache::Cache for the API documentation.

=head1 OPTIONS

See Cache::Cache for standard options.

=head1 PROPERTIES

See Cache::Cache for default properties.

=head1 SEE ALSO
