For instance the data object may want to increment its version number once it has successfully been commited to the database.  PersistentSession getSession()      Returns the session for which this data object is acting as a data base interface.  int getTransactionRowCount()      Returns the transaction count - i.e.  boolean getTransactionStatus()      Returns the transaction status. Constructor Detail PersistentSessionDO protected PersistentSessionDO(PersistentSession session)(Code) Parameters:   session - the session for which this data objectwill provide a database interface. PersistentSessionDO public PersistentSessionDO(ResultSet rs, ClassLoader loader) throws SQLException, IOException, ClassNotFoundException(Code) Parameters:   rs - Result set from which to instantiate the session. Parameters:   loader - The class loader to use when reconstructing the sessionfrom serialized data. exception:   SQLException - If a database connection error occurs. exception:   IOException - If the serialized session cannot be re-instantiated from thepersistent data. exception:   ClassNotFoundException - If a class associated with the serialized session cannotbe found. Method Detail executeDelete public void executeDelete(DBConnection conn) throws SQLException(Code) Method to delete an object from the database. Parameters:   conn - Database connection. exception:   java.sql.SQLException - If a database access erroroccurs. executeInsert public void executeInsert(DBConnection conn) throws SQLException(Code) Inserts the session into the database. Parameters:   conn - Database connection. exception:   java.sql.SQLException - If a database access erroroccurs or if the session data could not be serialized. executeUpdate public void executeUpdate(DBConnection conn) throws SQLException(Code) Method to update contents of object in database. Parameters:   conn - Database connection. exception:   java.sql.SQLException - If a database access erroroccurs. finalizeDelete public void finalizeDelete(boolean success)(Code) If this object's executeDelete method was called then finalizeDelete is called with the status of the database transaction. Parameters:   success - true if the transaction succeededand this object was successfully deleted from thedatabase. finalizeInsert public void finalizeInsert(boolean success)(Code) If this object's executeInsert method was called then finalizeInsert is called with the status of the database transaction. This method allows the data object to perform any post processing if the transaction succeeded or failed. Parameters:   success - true if the transaction succeededand this object was successfully inserted into the database. finalizeUpdate public void finalizeUpdate(boolean success)(Code) If this object's executeUpdate method was called then finalizeUpdate is called with the status of the database transaction. For instance the data object may want to increment its version number once it has successfully been commited to the database. Parameters:   success - true if the transaction succeededand this object was successfully updated in the database. getSession PersistentSession getSession()(Code) Returns the session for which this data object is acting as a data base interface. the session getTransactionRowCount int getTransactionRowCount()(Code) Returns the transaction count - i.e. the number of rows affected in the transaction. getTransactionStatus boolean getTransactionStatus()(Code) Returns the transaction status. the transaction status.
