• How to pass non-fatal warnings from a library

  - by wRAR

  A library function parses a file and returns an object. If a parser encounters unknown data, missing values etc., it shouldn't throw an exception and stop parsing (because this is not fatal), but there should be a way to pass information about these things to a caller (so that warnings can be displayed in the UI, for example). How can these warning be returned? I'm thinking of passing a callback function/object into the library, are there any other possible solutions?

• Make error: target pattern contains no '%'. Stop.

  - by Derek

  Hi all. I have a project that I have been running on IRIX that builds fine with gmake. I copied the source and make files onto a Redhat machine, and running gmake gives me the error posted in the subject. This is during a part of the make that is building .d dependency files, and they are separated by a colon, which I have read is a no-no, but why does it work on one system and not the other? What is the fix? Thanks

• JsonIgnore attributes not working in ASP.NET?

  - by Geoffrey

  I've got an object in my project with circular references. I've put [JsonIgnore] above the field like so: [JsonIgnore] public virtual Foobar ChildObject { get; set; } I'm still getting circular reference errors when I serialize the object. The only fields that do not have JsonIgnore are string fields and should not cause this. Is there something else I need to do to get JsonIgnore to work? Thanks!

• problem understanding templates in c++

  - by hidayat

  Template code is not compiled until the template function is used. But where does it save the compiled code, is it saved in the object file from which used the template function in the first place? For example, main.cpp is calling a template function from the file test.h, the compiler generates an object file main.o, Is the template function inside the main.o file? because template code is not inlined, is it?

• PHP ORM's, multiple tables and efficiency

  - by sunwukung

  Let's say I have a data mapper function that aggregates multiple tables and generates an object instance from that data. The mapper has a typical save() method which delegates to update/insert. When the mapper executes save - ideally it isolates object fields that have been modified, thus preventing the code from blanket bombing the database. How would you go about this?

• Get column name in jpa

  - by German

  Hi all, I have a query factory that takes a column name as an attribute in order to search for that column. Right now I'm passing the name of the column as a string, so it's kind of hardcoded. If the name of the column changes in the entity's annotation, that "hidden dependency" breaks up. Is there a way in jpa to retrieve the real name of the column and have it available at compile time, so I can use it in queries?

• Interpreter typing in C

  - by typus

  I'm developing an interpreter and I have some questions to it. I recently saw a small C interpreter that used a very simple struct like the below for all its objects/values in the language: struct Object { ubyte type; ubyte value; }; This struct can hold strings, integers, bools and lists (I think) used in the language the interpreter is working with. How can you get this Object struct to hold all these types?
