17.2. DistributedCallable API
The
DistributedCallable
interface is a subtype of the existing Callable
from java.util.concurrent.package, and can be executed in a remote JVM and receive input from Red Hat JBoss Data Grid. The DistributedCallable
interface is used to facilitate tasks that require access to JBoss Data Grid cache data.
When using the
DistributedCallable
API to execute a task, the task's main algorithm remains unchanged, however the input source is changed.
Users who have already implemented the
Callable
interface must extend DistributedCallable
if access to the cache or the set of passed in keys is required.

API
