Class TokenDAOProxy

java.lang.Object
  com.atlassian.crowd.model.token.TokenDAOProxy

All Implemented Interfaces:

TokenDAO, ObjectDao, java.util.EventListener, org.springframework.context.ApplicationListener

public class TokenDAOProxy
extends java.lang.Object
implements TokenDAO, org.springframework.context.ApplicationListener

Proxies the concrete TokenDAO implementations, and allows runtime swapping between implementations, along with copying of data between during swap.

Returns:

Class

save

public void save(java.lang.Object persistentObject)
          throws org.springframework.dao.DataAccessException

Description copied from interface: ObjectDao

Saves a new DAO object to the persistence store.

Specified by:

public void switchToMemory()

If the Hibernate DAO is in use, transparently switches to In-memory DAO. Does nothing if the In-memory DAO is already in use. Acquires write lock for safety.

public void switchToHibernate()

If the In-memory DAO is in use, transparently switches to Hibernate DAO. Does nothing if the hibernate DAO is already in use. Acquires write lock for safety.
