Class Transaction

java.lang.Object
  com.extentech.ExtenBean.Transaction

public class Transaction
extends java.lang.Object

Provides a simple transaction mechanism for DataObjects. The controller must create a transaction. then add DataObjects to the transaction to register them as part of the transaction. Begintrans() will initiate the saved state of the transacted objects. A call to commit iterates through the DataObjects and performs an updateObject() for each. If one update fails, the entire set of DataObjects is reset to its original (pre-begintrans()) state.
