Interface UpdateCallback

All Superinterfaces:

RowDeletable, RowInsertable, RowUpdateable, TableCreatable, TableDroppable

All Known Implementing Classes:

AbstractUpdateCallback

public interface UpdateCallback
extends TableCreatable, TableDroppable, RowInsertable, RowUpdateable, RowDeletable

An UpdateCallback is used by an UpdateScript to perform updates on a DataContext. Multiple updates (eg. insertion of several rows or creation of multiple tables) can (and should) be performed with a single UpdateCallback. This pattern guarantees that connections and/or file handles are handled correctly, surrounding the UpdateScript that is being executed.
