Interface Transaction.State

All Known Implementing Classes:

DiffTransactionState

Enclosing interface:

Transaction

public static interface Transaction.State

DataStore implementations can use this interface to externalize the state they require to implement Transaction Support.

The commit and rollback methods will be called as required. The intension is that several DataStores can share common transaction state (example: Postgis DataStores sharing a connection to the same database).
