getMapper

public <T> PersistenceMapper<T> getMapper(Class<T> clazz)

Description copied from interface: PersistenceMapperFactory

Returns the persistence mapper for objects of class clazz.

Note: It is highly recommended that clients cache the returned persistence mapper for as long as the transaction is active.

The persistence mapper must not be used across transaction boundaries. That is, a persistence mapper must not be used during a different transaction than the one during which it was created.
