/**
 * CActiveDataProvider implements a data provider based on ActiveRecord.
 *
 * CActiveDataProvider provides data in terms of ActiveRecord objects which are
 * of class {@link modelClass}. It uses the AR {@link CActiveRecord::findAll} method
 * to retrieve the data from database. The {@link criteria} property can be used to
 * specify various query options.
 *
 * CActiveDataProvider may be used in the following way:
 * <pre>
 * $dataProvider=new CActiveDataProvider('Post', array(
 *     'criteria'=>array(
 *         'condition'=>'status=1',
 *         'order'=>'create_time DESC',
 *         'with'=>array('author'),
 *     ),
 *     'pagination'=>array(
 *         'pageSize'=>20,
 *     ),
 * ));
 * // $dataProvider->getData() will return a list of Post objects
 * </pre>
 *
 * @property CDbCriteria $criteria The query criteria.
 * @property CSort $sort The sorting object. If this is false, it means the sorting is disabled.
 *
