How can I wrap a method so that I can kill its execution if it exceeds a specified timeout?

I have a method that I would like to call. However, I'm looking for a clean, simple way to kill it or force it to return if it is taking too long to execute. I'm using Java. to illustrate: logger.info("sequentially executing all batches..."); for (TestExecutor executor : builder.getExecutors()) { logger.info("executing batch..."); executor.execute(); } I figure the TestExecutor class should implement Callable and continue in that direction. But all i want to be able to do is stop executor.execute() if it's taking too long. Suggestions...? EDIT Many of the suggestions received assume that the

In c++ 11, how to invoke an arbitrary callable object?

由 北城以北 提交于 2019-11-26 23:29:11
问题 The concept of callable is defined in http://en.cppreference.com/w/cpp/concept/Callable. Suppose I have a callable object f that has one argument of type T* and return type void . f can be any callable type (a function object, a pointer to member function, a pointer to data member, etc). How can I invoke f ? Simply calling f(x) fails since f can be a pointer to member function or data member. Is there a simple way to call f ? One possible solution is std::bind(f, x)(), but this solution

When to use Spring @Async vs Callable controller (async controller, servlet 3)

问题 I would like to know the general use case of using @Async and Servlet 3 asynchronous request implementation in Spring using Callable. As I understand, @Async is for making any method (specifically, any service method) execute asynchronously. @Async void doSomething(String s) { // this will be executed asynchronously } and any controller which returns Callable @RequestMapping("/view") public Callable<String> callableWithView(final Model model) { return new Callable<String>() { @Override public

问题 I am using Java Callable Future in my code. Below is my main code which uses the future and callables - public class TimeoutThread { public static void main(String[] args) throws Exception { ExecutorService executor = Executors.newFixedThreadPool(5); Future<String> future = executor.submit(new Task()); try { System.out.println("Started.."); System.out.println(future.get(3, TimeUnit.SECONDS)); System.out.println("Finished!"); } catch (TimeoutException e) { System.out.println("Terminated!"); }

In a class there is a nested class as below: private final class CoverageCRUDaoCallable implements Callable<List<ClientCoverageCRU>> { private final long oid; private final long sourceContextId; private CoverageCRUDaoCallable(long oid, long sourceContextId) { this.oid = oid; this.sourceContextId = sourceContextId; } @Override public List<ClientCoverageCRU> call() throws Exception { return coverageCRUDao

The difference between the Runnable and Callable interfaces in Java

What is the difference between using the Runnable and Callable interfaces when designing a concurrent thread in Java, why would you choose one over the other? Jorge Ferreira See explanation here . The Callable interface is similar to Runnable, in that both are designed for classes whose instances are potentially executed by another thread. A Runnable, however, does not return a result and cannot throw a checked exception. Stephen C What are the differences in the applications of Runnable and Callable . Is the difference only with the return parameter present in Callable ? Basically, yes. See

What is a “callable”?

问题 Now that it\'s clear what a metaclass is, there is an associated concept that I use all the time without knowing what it really means. I suppose everybody made once a mistake with parenthesis, resulting in an \"object is not callable\" exception. What\'s more, using __init__ and __new__ lead to wonder what this bloody __call__ can be used for. Could you give me some explanations, including examples with the magic method ? 回答1: A callable is anything that can be called. The built-in callable
