See Cache::Backend for the usage synopsis.
$backend->store( 'namespace', 'foo', 'bar' );
my $bar = $backend->restore( 'namespace', 'foo' );
my $size_of_bar = $backend->get_size( 'namespace', 'foo' );
foreach my $key ( $backend->get_keys( 'namespace' ) )
{
$backend->delete_key( 'namespace', $key );
}
foreach my $namespace ( $backend->get_namespaces( ) )
{
$backend->delete_namespace( $namespace );
}
