15
 * ActiveFixture represents a fixture backed up by a [[modelClass|ActiveRecord class]] or a [[tableName|database table]].
16
 *
17
 * Either [[modelClass]] or [[tableName]] must be set. You should also provide fixture data in the file
18
 * specified by [[dataFile]] or overriding [[getData()]] if you want to use code to generate the fixture data.
19
 *
20
 * When the fixture is being loaded, it will first call [[resetTable()]] to remove any existing data in the table.
21
 * It will then populate the table with the data returned by [[getData()]].
22
 *
23
 * After the fixture is loaded, you can access the loaded data via the [[data]] property. If you set [[modelClass]],
24
 * you will also be able to retrieve an instance of [[modelClass]] with the populated data via [[getModel()]].
25
 *
26
 * @property TableSchema $tableSchema The schema information of the database table associated with this
27
 * fixture. This property is read-only.
