Example 1 with ThreadlessExecutor

use of org.apache.dubbo.common.threadpool.ThreadlessExecutor in project dubbo by alibaba.

the class AsyncRpcResult method get.

/**
 * This method will always return after a maximum 'timeout' waiting:
 * 1. if value returns before timeout, return normally.
 * 2. if no value returns after timeout, throw TimeoutException.
 *
 * @return
 * @throws InterruptedException
 * @throws ExecutionException
