Javadoc
PUBLIC:
Set whether to update the stored time an object was read when an object is updated.
When the read time is updated, it indicates to EclipseLink that the data in the object
is up to date. This means that cache invalidation checks will occur relative to the
new read time.
By default, the read time will not be updated when an object is updated.
Often it is possible to be confident that the object is up to date after an update
because otherwise the update will fail because of the locking policies in use.
