If you are using xoopsObject to manage the data access to your modules tables you must surely use this kind of code:
$myHandler = xoops_getmodulehandler('mytable', 'mymodule');
The problem is that sometimes you declare this kind of code somewhere and you can't access it somewhere else, for example from a function.
The other problem is that you have to repeat this kind of code each time you need a handler.
With this class, you can access to any table's handler from anywhere without multiplying the objects.
You just need to do something like this :
$oledrion_handlers = oledrion_handler::getInstance();
$count = $oledrion_handlers->h_oledrion_products->getRecommendedCount();
You can even access a handler like this:
$count = oledrion_handler::getInstance()->h_oledrion_products->getRecommendedCount();
The advantage, as I said, is that you can access your handlers from anywhere without creating several times the same object and all your handlers are centralized in one place.
Handlers are loaded on demand and stay in memory for further use.
