 org.apache.commons.betwixt.strategy.IdStoringStrategy
All known Subclasses: org.apache.commons.betwixt.strategy.DefaultIdStoringStrategy,
| IdStoringStrategy | | abstract public class IdStoringStrategy (Code) | | Pluggable strategy for id storage management.
It is possible to use this strategy for innovative
active storage storage strategies as well as passive ones.
For example, it is possible to have some beans map to
references without ever being fully mapped.
