net.sf.hibernate.odmg
Class Database

java.lang.Object
  net.sf.hibernate.odmg.Database

All Implemented Interfaces:

org.odmg.Database

---

public class Database

extends Object

implements org.odmg.Database

Implements the ODMG Database API. This provides operations for persisting and deleteing objects, binding names to objects and looking up objects by name.

Applications may create an instance by calling Implementation.newDatabase() or by instantiating this class directly. The application should then call open() to associate it with an existing Hibernate SessionFactory.

Instances maintain an association between Threads and Transactions.

Implementation, Transaction

Get the Session underlying the Transaction associated with the current thread.

---

getSessionFactory

public SessionFactory getSessionFactory()

Get the SessionFactory underlying this Database.

---

currentTransaction

public Transaction currentTransaction()

Get the Transaction associatedm with the current thread.

open

public void open(String name,
                 int accessMode)
          throws org.odmg.ODMGException

Specify the underlying SessionFactory, by passing a JNDI name. The accessMode is ignored by Hibernate.

Specified by:

open in interface org.odmg.Database

Close the Database (but not the underlying SessionFactory).

Specified by:

close in interface org.odmg.Database

Throws:

org.odmg.ODMGException

---

bind

public void bind(Object object,
                 String name)
          throws org.odmg.ObjectNameNotUniqueException
