/**
* Defines strategies for fetching data from the database.
* The EAGER strategy is a requirement on the persistence
* provider runtime that data must be eagerly fetched. The
* LAZY strategy is a hint to the persistence provider
* runtime that data should be fetched lazily when it is
* first accessed. The implementation is permitted to eagerly
* fetch data for which the LAZY strategy hint has been
* specified. In particular, lazy fetching might only be
* available for {@link Basic} mappings for which property-based
* access is used.
*
*
* Example:
* @Basic(fetch=LAZY)
* protected String getName() { return name; }
*
*
* @since Java Persistence 1.0
