问题 It appears that one cannot resume the execution of test once you hit the raise the user defined exception in Python. But in my scenario I want to check error occurred for different input values. But Current implementation is restricting to continue the check error for the different input vectors. However, before coming up with some sort of convoluted solution to my problem, I figured I would ask the experts and see if there is something I'm missing. Unfortunately, I cannot change this

问题 We use Twitter futures (as part of the Finagle stack) and I don't like the concept of using (business) exceptions to control the flow of our application, because exceptions don't show up in method signatures. So I had the idea to use Future[Either[A,B]] as a replacement. But I have some problems in using for comprehensions over futures with this concept: E.g. we have a repository method: def getUserCredentialsByNickname(nickname: String): Future[Either[EntityNotFound, UserCredentials]] and a

问题 This question already has answers here : How to get Exception Error Code in C# (5 answers) Closed 6 years ago . Is there a way that i can get the corresponding error code of an Exceptions ? I need the thrown exceptions error code instead of its message , so that i based on the error code i show the right message to the user. 回答1: If you're looking for the win32 error code, that's available on the Win32Exception class catch (Win32Exception e) { Console.WriteLine("ErrorCode: {0}", e.ErrorCode);

问题 I have a number of points which make getOrthodromicDistance method to fail with exception in geotools lib, while these points are valid lat lon points: Point which throws the exception (lat,lon): val p1= (5.318765,-75.786109) val p2= (-6.32907,106.09254) eg exception: No convergence for points 75°47,2'W 06°19,7'S and 106°05,6'E 05°19,1'N. java.lang.ArithmeticException: No convergence for points 75°47,2'W 06°19,7'S and 106°05,6'E 05°19,1'N. at org.geotools.referencing.GeodeticCalculator

问题 I've seen several approaches of exception handling. Two most common patterns I've seen are: try catch on every function, log the exception and rethrow try catch on the top most level (Like main function), log the exception and rethrow Which is a better practice if there is one? Or what situations would you choose one approach over the another? 回答1: This depends on your application and is a design choice, though option 1 is very messy. You should only catch exceptions you are prepared to

问题 I am using MUPDF for an android project, but there is an issue by some android users. I got report as following: java.lang.UnsupportedOperationException: Not supported E/AndroidRuntime( 4677): at com.odilogy.mupdf.ReaderView.getSelectedView(ReaderView.java:664) E/AndroidRuntime( 4677): at android.widget.AdapterView.onInitializeAccessibilityEvent(AdapterView.java:951) E/AndroidRuntime( 4677): at android.widget.AdapterView.onRequestSendAccessibilityEvent(AdapterView.java:926) E/AndroidRuntime(

问题 I am running several tensorflow inferences using sess.run() in a loop and it happens that some inferences are too heavy for my GPU. I get errors like : 2019-05-23 15:37:49.582272: E tensorflow/core/common_runtime/executor.cc:623] Executor failed to create kernel. Resource exhausted: OOM when allocating tensor of shape [306] and type float I would like to be able to catch these specific OutOfMemory errors but not other errors (which may be due to a wrong input format or a corrupted graph.)

问题 try { x = session.load(...); y = x; } catch(Exception e) { //do something } If the key is not present, will load(...) throw an exception right away will return a proxy and then throw an exception when the object is trying to be obtained from the db later? Also, in the code above, if the execution reaches the assignment y = x, is it guaranteed that at that point, x is not null? Are there situations where x can be null at that point? 回答1: In short: x will not be null after the load, so neither

问题 I recently published an app to the market place. From the developers console it seems about 1-2% of my users are having this issue. 1-2% is small but people are more inclined to leave comments when something doesn't work rather than when it does which could negatively effect downloads. Unfortunately the developers console only lists the platform as 'other', but my app is available to those with SDK 1.6+. I'm also unable to recreate this issue and no user has contacted me directly so I'm

问题 I need to programatically check whether a nested property/function result in a lambda expression is null or not. The problem is that the null could be in any of the nested subproperties. Example. Function is: public static bool HasNull<T, Y>(this T someType, Expression<Func<T, Y>> input) { //Determine if expression has a null property } Use: person.HasNull(d=>d.addressdetails.Street) person.HasNull(d=>d.addressdetails[1].Street) person.HasNull(d=>d.addressdetails.FirstOrDefault().Street)
