Class TActiveRecordManager

Description
Description | Methods (details)

TActiveRecordManager provides the default DB connection, default object state registry, default active record gateway, and table meta data inspector.

You can provide a different registry by overriding the createObjectStateRegistry() method. Similarly, override createRecordGateway() for default gateway and override createMetaDataInspector()for meta data inspector.

The default connection can be set as follows: 

  1.  TActiveRecordManager::getInstance()->setDbConnection($conn);
    2.
All new active record created after setting the DbConnection will use that connection.

The onInsert(), onUpdate(), onDelete() and onSelect() events are raised before their respective command are executed.
