Return true if the template is cached as static html. It's useful to drastically improve the loading speed of the template.
Example:
$view = new View;
if( !$view->is_cached('test') ){
... query and heavy operation ...
$view->assign( "list", $query_results );
}
$view->draw( 'test' );
if( !$view->is_cached('test') ){
... query and heavy operation ...
$view->assign( "list", $query_results );
}
$view->draw( 'test' );
