-/**
- * Base class for active records.
- *
- * An active record creates an object that wraps a row in a database table
- * or view, encapsulates the database access, and adds domain logic on that data.
- *
- * The essence of an Active Record is an object model of the
- * domain (e.g. products, items) that incorporates both behavior and
- * data in which the classes match very closely the record structure of an
- * underlying database. Each Active Record is responsible for saving and
- * loading to the database and also for any domain logic that acts on the data.
- *
- * The Active Record provides methods that do the following:
- * 1. Construct an instance of the Active Record from a SQL result set row.
- * 2. Construct a new instance for later insertion into the table.
- * 3. Finder methods to wrap commonly used SQL queries and return Active Record objects.
- * 4. Update the database and insert into it the data in the Active Record.
- *
- * Example:
- * <code>
- * class UserRecord extends TActiveRecord
- * {
- * const TABLE='users'; //optional table name.
- *
- * public $username; //corresponds to the fieldname in the table
- * public $email;
- *
- * //returns active record finder instance
- * public static function finder($className=__CLASS__)
- * {
- * return parent::finder($className);
- * }
- * }
- *
- * //create a connection and give it to the ActiveRecord manager.
- * $dsn = 'pgsql:host=localhost;dbname=test';
- * $conn = new TDbConnection($dsn, 'dbuser','dbpass');
- * TActiveRecordManager::getInstance()->setDbConnection($conn);
- *
- * //load the user record with username (primary key) 'admin'.
- * $user = UserRecord::finder()->findByPk('admin');
- * $user->email = 'admin@example.org';
- * $user->save(); //update the 'admin' record.
