How to specify Http Request timeout parameter on Java servlet container

由 淺唱寂寞╮ 提交于 2019-11-26 22:00:00
问题 I'm trying to understand where I can configure a request timeout for all requests arriving to a servlet of mine (or all of my servlets)? Is that, as I think, a container property? Also, how does this affect different browsers? Do they all comply to the parameter the container dictates? Or maybe the request timeout time isn't even something I can control and each browser decides on this on its own? (Just to be clear I'm not talking about session timeout) 回答1: The timeout from a client (i.e.

Copy map values to vector in STL

由 老子叫甜甜 提交于 2019-11-26 21:38:40
Working my way through Effective STL at the moment. Item 5 suggests that it's usually preferable to use range member functions to their single element counterparts. I currently wish to copy all the values in a map (i.e. - I don't need the keys) to a vector. What is the cleanest way to do this? You can't easily use a range here becuase the iterator you get from a map refers to a std::pair, where the iterators you would use to insert into a vector refers to an object of the type stored in the vector, which is (if you are discarding the key) not a pair. I really don't think it gets much cleaner

ItemContainerGenerator.ContainerFromItem() returns null?

由 谁都会走 提交于 2019-11-26 20:52:30
I'm having a bit of weird behavior that I can't seem to work out. When I iterate through the items in my ListBox.ItemsSource property, I can't seem to get the container? I'm expecting to see a ListBoxItem returned, but I only get null. Any ideas? Here's the bit of code I'm using: this.lstResults.ItemsSource.ForEach(t => { ListBoxItem lbi = this.lstResults.ItemContainerGenerator.ContainerFromItem(t) as ListBoxItem; if (lbi != null) { this.AddToolTip(lbi); } }); The ItemsSource is currently set to a Dictionary and does contain a number of KVPs. Phred Menyhert I found something that worked better

c++ template class; function with arbitrary container type, how to define it?

由 我怕爱的太早我们不能终老 提交于 2019-11-26 19:30:40
问题 Okay, simple template question. Say I define my template class something like this: template<typename T> class foo { public: foo(T const& first, T const& second) : first(first), second(second) {} template<typename C> void bar(C& container, T const& baz) { //... } private: T first; T second; } The question is about my bar function... I need it to be able to use a standard container of some sort, which is why I included the template/typename C part, to define that container type. But apparently
