Method Details

onSuccess

void onSuccess(@Nullable T value)

onCancel

void onCancel(Throwable t)

The internal state machine invokes this method when a syscall is interrupted due to a suspension, or a network error.

In case the user code is blocked on a lock, the implementation of this method should unblock it.

of

static <T> SyscallCallback<T> of(Consumer<T> onSuccess,
 Consumer<Throwable> onFailure)

ofVoid

static SyscallCallback<Void> ofVoid(Runnable onSuccess,
 Consumer<Throwable> onFailure)

mappingTo

static <T,
R> SyscallCallback<T> mappingTo(Function<T,R> mapper,
 SyscallCallback<R> callback)

completingFuture

static <T> SyscallCallback<T> completingFuture(CompletableFuture<T> fut)
