Methods

methodpublic__construct(array $config) : void

Parameters
NameTypeDescription
$configarray
methodpublic__sleep() : array

Store data, class names, and state in serialized object

Returns
TypeDescription
array
methodpublic__wakeup() : void

Setup to do on wakeup.

A de-serialized Rowset should not be assumed to have access to a live database connection, so set _connected = false.
