public interface MainThreadExecutable

Interface to execute Runnable and Callable in the main thread of the underlying RPC endpoint.

This interface is intended to be implemented by the self gateway in a RpcEndpoint implementation which allows to dispatch local procedures to the main thread of the underlying RPC endpoint.

方法概要

限定符和类型	方法和说明
<V> CompletableFuture<V>	callAsync(Callable<V> callable, java.time.Duration callTimeout) Execute the callable in the main thread of the underlying RPC endpoint and return a future for the callable result.
void	runAsync(Runnable runnable) Execute the runnable in the main thread of the underlying RPC endpoint.
void	scheduleRunAsync(Runnable runnable, long delay) Execute the runnable in the main thread of the underlying RPC endpoint, with a delay of the given number of milliseconds.

方法详细资料

runAsync

void runAsync(Runnable runnable)

Execute the runnable in the main thread of the underlying RPC endpoint.

参数:

runnable - Runnable to be executed

callAsync

<V> CompletableFuture<V> callAsync(Callable<V> callable,
                                   java.time.Duration callTimeout)

Execute the callable in the main thread of the underlying RPC endpoint and return a future for the callable result. If the future is not completed within the given timeout, the returned future will throw a TimeoutException.

类型参数:

V - Return value of the callable

参数:

callable - Callable to be executed

callTimeout - Timeout for the future to complete

返回:

Future of the callable result

scheduleRunAsync

void scheduleRunAsync(Runnable runnable,
                      long delay)

Execute the runnable in the main thread of the underlying RPC endpoint, with a delay of the given number of milliseconds.

参数:

runnable - Runnable to be executed

delay - The delay, in milliseconds, after which the runnable will be executed
