Package io.smallrye.faulttolerance.core.async

Class FutureExecution<V>

java.lang.Object

io.smallrye.faulttolerance.core.async.FutureExecution<V>

All Implemented Interfaces:

FaultToleranceStrategy<Future<V>>

public class FutureExecution<V>
extends Object
implements FaultToleranceStrategy<Future<V>>

Unlike ThreadOffload, this is supposed to be the first strategy in the chain. The remaining strategies are executed on an extra thread. This allows using synchronous execution of other strategies to implement Future-based @Asynchronous invocations, with two exceptions:

• timeouts, where FutureTimeout is needed in front of Timeout;
• bulkheads, where FutureBulkhead is used instead of Bulkhead.

apply

public Future<Future<V>> apply(FaultToleranceContext<Future<V>> ctx)

Description copied from interface: FaultToleranceStrategy

Apply the fault tolerance strategy around the target Callable. The Callable is wrapped in an FaultToleranceContext.

Specified by:

apply in interface FaultToleranceStrategy<V>

Parameters:

ctx - the InvocationContext wrapping the Callable guarded by this fault tolerance strategy

Returns:

result computed by the target Callable
