Package org.apache.sshd.common.future

Interface VerifiableFuture<T>

Type Parameters:

T - Type of verification result

All Known Subinterfaces:

AuthFuture, ConnectFuture, IoReadFuture, IoWriteFuture, KeyExchangeFuture, OpenFuture

All Known Implementing Classes:

AbstractIoWriteFuture, ChannelAsyncInputStream.IoReadFutureImpl, DefaultAuthFuture, DefaultConnectFuture, DefaultKeyExchangeFuture, DefaultOpenFuture, DefaultVerifiableSshFuture, IoWriteFutureImpl, Nio2DefaultIoWriteFuture, PendingWriteFuture, SimpleIoOutputStream.DefaultIoWriteFuture

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface VerifiableFuture<T>

Represents an asynchronous operation whose successful result can be verified somehow. The contract guarantees that if the verifyXXX method returns without an exception then the operation was completed successfully

Method Summary

Modifier and Type	Method	Description
default T	verify()	Wait Long.MAX_VALUE msec.
T	verify(long timeoutMillis)	Wait and verify that the operation was successful
default T	verify(long timeout, java.util.concurrent.TimeUnit unit)	Wait and verify that the operation was successful
default T	verify(java.time.Duration timeout)	Wait and verify that the operation was successful
