| 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
Basic mappings for which property-based
access is used.
Example:
@Basic(fetch=LAZY)
protected String getName() { return name; }
