Method Detail

markPersistentType

public <T extends EntityComponent> void markPersistentType(java.lang.Class<T> type)

Description copied from interface: PersistentEntityData

Specified by:

markPersistentType in interface PersistentEntityData

execute

protected void execute(java.lang.String statement)
                throws java.sql.SQLException

java.sql.SQLException

getSession

protected SqlSession getSession()
                         throws java.sql.SQLException

Throws:

java.sql.SQLException

lookupDefaultHandler

protected <T extends EntityComponent> ComponentHandler<T> lookupDefaultHandler(java.lang.Class<T> type)

Description copied from class: DefaultEntityData

When no specific type handler exists, this attempts to find an appropriate handler. Default implementation returns a new MapComponentHandler.

Overrides:
