Method Detail

createInstance

public static HibernateUtil createInstance(Properties propBundle)

getInstance

public static HibernateUtil getInstance()

openSession

public static org.hibernate.classic.Session openSession()
                                                 throws org.hibernate.HibernateException

Return a new session which is independent of the session created by getSession.

Returns:

a new session

Throws:

org.hibernate.HibernateException

dialectIsMysql

public static boolean dialectIsMysql()

checkAndRepairLineIndex

public static void checkAndRepairLineIndex()

getJdbcConnection

public Connection getJdbcConnection()
                             throws SQLException

Return a connection to the configured database to be used with utilities like Liquibase.

Returns:

a connection to the configured database.

Throws:

SQLException

getSession

public static org.hibernate.classic.Session getSession()
                                                throws org.hibernate.HibernateException

Get the session currently associated with the thread. This is the POSper legacy method to retrieve a session. We must be aware that the caller can never be sure if he will get the same session as with a previous call or a brand new session because another party caaling this method might have closed the session or the session has been closed because a Hibernate exception has occurred.

Returns:

Throws:

org.hibernate.HibernateException

getNewSession

public static org.hibernate.classic.Session getNewSession()
                                                   throws org.hibernate.HibernateException

Closes the current session and retturns a new one. We call this method when a view is being (re)entered. A log entry is created if configured the log4j properties file. Use with care: closing a session detaches all objects, and rolls back an open transaction (at least I think so)

Returns:

a session replacing the session previously associated with the thread.

Throws:

org.hibernate.HibernateException

closeSession

public static void closeSession()

Close the current session. A log entry is created if this is configured in the log4j properties file.

getCurrentSession

public static org.hibernate.classic.Session getCurrentSession()

getSessionFactory

public static org.hibernate.SessionFactory getSessionFactory()

getHbm2ddlType

public String getHbm2ddlType()

Returns:

the hbm2ddlType

setHbm2ddlType

public void setHbm2ddlType(String hbm2ddlType)

Parameters:

hbm2ddlType - the hbm2ddlType to set

reInitialize

public void reInitialize()

Completely shut down the session factory and start again.

disconnect

public void disconnect()

getDbType

public String getDbType()

Returns:

the database type based on the driver lib

dbIsEmpty

public boolean dbIsEmpty()

We check if the database contains any tables on Iniitialisation to be sure we have an empty schema when we create a new database.

Returns:

true if the configured schema contains no tables, false otherwise.

getDbName

public String getDbName()
