Package org.apache.sshd.common.future

Interface VerifiableFuture<T>

Type Parameters:

T - Type of verification result

All Known Subinterfaces:

CancelFuture, IoReadFuture, IoWriteFuture

All Known Implementing Classes:

AbstractIoWriteFuture, DefaultCancelFuture, DefaultCancellableSshFuture, DefaultIoConnectFuture, DefaultVerifiableSshFuture

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

Parameters:

options - Optional CancelOptions defining the behavior on time-out or interrupt; ignored if the future is not Cancellable.

Returns:

The (same) future instance

Throws:

IOException - If failed to verify successfully on time
