The profiler class is the adapter's default profiler class, * Zend_Db_Profiler. * * An instance of Zend_Db_Profiler sets the adapter's instance to that * object. The profiler is enabled and disabled separately. * * An associative array argument may contain any of the keys 'enabled', * 'class', and 'instance'. The 'enabled' and 'instance' keys correspond to the * boolean and object types documented above. The 'class' key is used to name a * class to use for a custom profiler. The class must be Zend_Db_Profiler or a * subclass. The class is instantiated with no constructor arguments. The 'class' * option is ignored when the 'instance' option is supplied. * * An object of type Zend_Config may contain the properties 'enabled', 'class', and * 'instance', just as if an associative array had been passed instead. * * @param Zend_Db_Profiler|Zend_Config|array|boolean $profiler db profiler * @return Zend_Db_Adapter_Abstract Provides a fluent interface * @throws Zend_Db_Profiler_Exception if the object instance or class specified * is not Zend_Db_Profiler or an extension of that class. */ public function setProfiler($profiler) { return $this->_adapter->setProfiler($profiler); }
