1.2.3. Per-Invocation Flags Example
In a use case for Red Hat JBoss Data Grid, where a write operation, such as
put(), must not return the previous value, the IGNORE_RETURN_VALUES flag is used. This flag prevents a remote lookup (to get the previous value) in a distributed environment, which in turn prevents the retrieval of the undesired, potential, previous value. Additionally, if the cache is configured with a cache loader, this flag prevents the previous value from being loaded from its cache store.
An example of using the
IGNORE_RETURN_VALUES flag is:
Cache cache = ...
cache.getAdvancedCache()
.withFlags(Flag.IGNORE_RETURN_VALUES)
.put("local", "only")
