Package io.smallrye.faulttolerance.core.async

Class CompletionStageExecution<V>

java.lang.Object

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

All Implemented Interfaces:

FaultToleranceStrategy<CompletionStage<V>>

public class CompletionStageExecution<V>
extends Object
implements FaultToleranceStrategy<CompletionStage<V>>

Unlike FutureExecution, this is supposed to be the next to last strategy in the chain (last being Invocation). To implement CompletionStage-based @Asynchronous invocations, each synchronous strategy has a CompletionStage counterpart that is used. The CompletionStage strategies never block and hence may be executed on the original thread.

apply

public CompletionStage<V> apply(InvocationContext<CompletionStage<V>> ctx)

Description copied from interface: FaultToleranceStrategy

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

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
