exception

问题 I have a table with rows created by ng-repeat. Table headers have an ng-click that sets the predicate for the sorting (the function also determines direction, asc/desc). The sorting works fine, but for some reason I get exceptions from jQuery every time I change the predicate and the sort fires. Here is a plunkr example of what I am doing : http://plnkr.co/edit/qfNcm9RPQSsNgqmm3TYS?p=preview As you can see in the plnkr, the ng-repeat is pretty simple. The ng-repeat in our project is similar

问题 Consider the following C++ code: class MyException {}; void someFunction() { try { /// ... code that may throw } catch(std::exception& e ) { throw MyException(); } } Question Is the exception e absorbed at the beginnging of the catch block or at the end of the catch block? In the second case throwing the new exception would result in having two exceptions in flight, what is not what I want. I want to absorb the std::exception and start one of my own type. 回答1: No. That's how one should do it.

问题 In my unit tests I need to perform deep equality tests of two objects, which are expected to be identical. During the tests I discover some interesting fields in system types that break my code. Exception._xcode is the most recent one. Here are a couple of facts about this field: It is initialized to -532459699 in all the Exception constructors, except the custom deserialization constructor, where it is simply never mentioned (thanks Reflector). It is not marked with the NonSerialized

问题 Is there some crossplatform c-library for exception handling (to implement try / catch in C)? I'm also looking for documentation how it's realized in c++ (how the interrupts are masking or something like this) 回答1: You can try exceptions4c; it's an exception handling library in ANSI C that supports: throw , try , catch , finally and a few more goodies. For example, it supports the Dispose pattern , so you can automatically release resources. You can also handle signals (such as SIGFPE and

问题 My dump file contains OutOfMemoryException but all the object fields seem to be null.

问题 I am using Path.Combine, and one of the strings contain a Unicode characters. I get {System.ArgumentException} exception; illegal characters in path. According to MSDN filepath/name can have unicode characters. Why do I get this exception? Edit: Here is the code: Path.Combine("C:\PDM\Silver","Amabel Bender QQQ") 回答1: I figured out the problem. The second string contains a "tab" character in it causing the exception. (that didn't showed up when I pasted the string here) Thanks everyone and

My CursorAdapter implements

问题 I have a std::exception_ptr with an exception inside it. I am going to invoke std::rethrow_exception to get the actual exception, will the exception be valid after the catch statement? My guess here is that since I still hold the std::exception_ptr it will still be valid. See the example: std::exception_ptr ePtr = initialize_somewhere_else(); std::runtime_error* a=NULL; try { std::rethrow_exception(ePtr); } catch(std::runtime_error& e) { a = &e; } std::cout << a << ", " << a->what() << std:
