supportsCompositePrimaryKey?

optional supportsCompositePrimaryKey?: boolean

Set to true if connector is able to work with resources which have several columns marked as AdminForthResourceColumn.primaryKey (composite primary key). Such connector must build WHERE clause from pkValues argument of IAdminForthDataSourceConnector.updateRecordOriginalValues and IAdminForthDataSourceConnector.deleteRecord instead of using getPrimaryKey().

IAdminForthDataSourceConnector.supportsCompositePrimaryKey
