Examples of org.dmlite.model.action.Transaction

org.dmlite.model.action.Transaction
Encapsulates a transaction in a session. A transaction keeps a history of actions on entities. A transaction may be executed or undone. To be successful, all transaction actions must be successful. Domain model observers are informed about the execute or undo events. @author Dzenan Ridjanovic @version 2006-11-20
