Class NoOpTransaction

java.lang.Object

org.sormula.Transaction

org.sormula.NoOpTransaction

public class NoOpTransaction
extends Transaction

A Transaction that does not perform Connection.commit() or Connection.rollback(). It does notify TransactionListener objects for begin(), commit(), and rollback().

This class is useful for cached operations when connection autocommit is true (that is when no sql transaction is used).

Set on existing database:

 Database database = new Database(...);
 database.setTransaction(new NoOpTransaction(database.getConnection()));
 

Use through inheritance:

 public class MyDatabase extends Database
 {
     public MyDatabase(...) throws SormulaException
     {
         super(...);
     }
 
      @Override
     protected Transaction initTransaction(Connection connection) throws SormulaException
     {
         return new NoOpTransaction(connection);
     }
 }
