2.3.4. Per-Invocation Flags Example

In a use case for JBoss Data Grid, where a write operation, such as put(), should not return the previous value, two flags are used. The two flags prevent 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, the two flags prevent the previous value from being loaded from its cache store.

An example of using the two flags is:

	Cache cache = ...
	cache.getAdvancedCache()
	   .withFlags(Flag.IGNORE_RETURN_VALUES)
	   .put("local", "only")

	Cache cache = ...
	cache.getAdvancedCache()
	   .withFlags(Flag.IGNORE_RETURN_VALUES)
	   .put("local", "only")
