MainThreadExecutable (Flink : RPC : Core 2.0.0 API)

All Known Subinterfaces:

RpcServer
```
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.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`<V> CompletableFuture<V>`	`callAsync(Callable<V> callable, 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.

- Method Detail
  - runAsync
```
void runAsync(Runnable runnable)
```
    Execute the runnable in the main thread of the underlying RPC endpoint.
    
    Parameters:
    
    runnable - Runnable to be executed
  - callAsync
```
<V> CompletableFuture<V> callAsync(Callable<V> callable,
                                   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.
    
    Type Parameters:
    
    V - Return value of the callable
    
    Parameters:
    
    callable - Callable to be executed
    
    callTimeout - Timeout for the future to complete
    
    Returns:
    
    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.
    
    Parameters:
    
    runnable - Runnable to be executed
    
    delay - The delay, in milliseconds, after which the runnable will be executed
