Constructor Detail

DbUtil

public DbUtil(java.util.Properties properties)

Creates a new instance of the DbUtil object. Applications should not create instances of this object because the creator of XBRLDatabaseAccessApp already creates the instance of DbUtil object.

Parameters:

properties - Properties object. Extra properties for the Hibernate connection to the database.

Method Detail

getSessionFactory

public org.hibernate.SessionFactory getSessionFactory(RegisterExtraClasses[] registers)

gets or creates a session factory. If the session factory does not exist it is created and stored for later use.

The parameter is optional (can be null), if supplied it is an array of objects that implements the RegisterExtraClasse interface and this causes the configuration object to load more classes in the data model.

Returns null in case there are Hibernate exceptions during the connection to the database.

Parameters:

registers - Optional parameter, can be null.

Returns:

SessionFactory suitable for generating sessions
