问题 This is a program that reads information site for previous format it uses recursion and executor.It works fine,my problem is to test whether the program is completed and success notification. public class NewClass { static String levels[] = { "div.col-md-9 li a", "div#sidebar ul li a" }; static String links = ""; private void getRecursive(String href, int level, final ExecutorService executor) { if (level > levels.length - 1) { return; } Document doc; try { doc = Jsoup.connect(href).get();

Assisting Agda's termination checker

由 情到浓时终转凉″ 提交于 2019-11-27 20:37:22
Suppose we define a function f : N \to N f 0 = 0 f (s n) = f (n/2) -- this / operator is implemented as floored division. Agda will paint f in salmon because it cannot tell if n/2 is smaller than n. I don't know how to tell Agda's termination checker anything. I see in the standard library they have a floored division by 2 and a proof that n/2 < n. However, I still fail to see how to get the termination checker to realize that recursion has been made on a smaller subproblem. Agda's termination checker only checks for structural recursion (i.e. calls that happen on structurally smaller

How terminate child processes when parent process terminated in C#

由 坚强是说给别人听的谎言 提交于 2019-11-27 13:15:06
问题 Task: Auto kill all child processes if parent process terminate. Parent procees can be terminated not only in correct way, but also by killing in ProcessExplorer, for example. How can I do it? Similar question in С topic advice to use Job objects. How to use it in C# without exporting external DLL? I tried to use Job Objects. But this code doesn't work properly: var job = PInvoke.CreateJobObject(null, null); var jobli = new PInvoke.JOBOBJECT_BASIC_LIMIT_INFORMATION(); jobli.LimitFlags =

Using an iterator to Divide an Array into Parts with Unequal Size

I have an array which I need to divide up into 3-element sub-arrays. I wanted to do this with iterators, but I end up iterating past the end of the array and segfaulting even though I don't dereference the iterator . given: auto foo = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; I'm doing: auto bar = cbegin(foo); for (auto it = next(bar, 3); it < foo.end(); bar = it, it = next(bar, 3)) { for_each(bar, it, [](const auto& i) { cout << i << endl; }); } for_each(bar, cend(foo), [](const auto& i) { cout << i << endl; }); Now I can solve this by defining a finish iterator: auto bar = cbegin(foo); auto finish

Better termination for s(X)-sum

由 混江龙づ霸主 提交于 2019-11-27 07:48:14
问题 (Let me sneak that in within the wave of midterm questions.) A common definition for the sum of two natural numbers is nat_nat_sum/3 : nat_nat_sum(0, N, N). nat_nat_sum(s(M), N, s(O)) :- nat_nat_sum(M, N, O). Strictly speaking, this definition is too general, for we have now also success for ?- nat_nat_sum(A, B, unnatural_number). Similarly, we get the following answer substitution: ?- nat_nat_sum(0, A, B). A = B. We interpret this answer substitution as including all natural numbers and do

How to know whether app is terminated by user or iOS (after 10min background)

How to know whether app is terminated by user or by iOS when restart app> 'By user' means "by Double-clicking Home Button and pressing - button". killed by user 'By iOS' means "app become background running state, and iOS terminate app after 10 mins" If your app is in suspended state the applicationWillTerminate will never get called regardless who killed the app iOS or user. Your applicationWillTerminate will only call when your app is in background and it gets killed (either by iOS or user) the term background means that it is running in background not in suspended state. Just read this

How to force stop my android application programmatically?

I'd like to force stop my Android application when I click closeButton. This is my code. protected void onCreate(Bundle savedInstanceState) { this.setContentView(R.layout.layoutxml); this.closeButton = (Button)this.findViewById(R.id.close); this.closeButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { finish(); } }); } This finishes my application. If I go to Settings -> Applications -> Manage applications -> <my application name> , I can see the 'Force Stop' button is enabled. Does this mean my application was not stopped completely? How can I finish my
