Generate DTOs from Object

阅读更多关于 Generate DTOs from Object

I want to auto gen some DTOs from some of my existing objects, I was wondering if there already exist a Resharper, DevExpress or VSX open source to use, I need a tool to look into my code and let me choose which properties I want to include in my DTO and then generate a class based on that... This is kind of a hack but you could use Visual Studio/Resharper to Extract an interface from the class, then create a DTO class and derive from the interface, then use Visual Studio to auto implement the interface members (then, optionally remove the interface). Another opinion would be to use some

Viewing the code generated by @synthesize for getter/setter

阅读更多关于 Viewing the code generated by @synthesize for getter/setter

问题 Is it possible to view the exact code generated by @synthesize? 回答1: You can read the Clang compiler source to see the C++ code that generates the getter and setter methods: http://llvm.org/svn/llvm-project/cfe/trunk/lib/CodeGen/CGObjC.cpp It's pretty cryptic but that's the most accurate way of seeing the code generated. You can also look at the objc_getProperty and objc_setProperty implementations in Apple's runtime implementation. While not literally the same as the code that is generated,

Looking for a java code generation library [closed]

阅读更多关于 Looking for a java code generation library [closed]

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . What is/are "good" java code generation libs? I found a generation part in JaxMe, but it's poor and old. I like to generate java code through java code. So basically use a lib to tell that it has to generate a

Why are unnecessary atomic loads not optimized away?

阅读更多关于 Why are unnecessary atomic loads not optimized away?

问题 Let's consider this trivial code: #include <atomic> std::atomic<int> a; void f(){ for(int k=0;k<100;++k) a.load(std::memory_order_relaxed); } MSVC, Clang and GCC all perform 100 loads of a, while it seems obvious it could have been optimized away. I expected the function f to be a nop (See generated code here) Actually, I expected this code generation for a volatile atomic: volatile std::atomic<int> va; void g(){ for(int k=0;k<100;++k) va.load(std::memory_order_relaxed); } Why do compilers

Eclipse generate getter/setter for domain objects and classmembers with 'm' suffix

阅读更多关于 Eclipse generate getter/setter for domain objects and classmembers with 'm' suffix

问题 I have a small question regarding generated getter and setter methods in my domain objects. I want to use a common style guide for my source code. One part of that style guide says that I start each class member name with the prefix 'm' for member. class User{ String mName; List<Call> mAllCall; List<Geo> mAllGeo; Unfortunately I have a couple of classes with many more member variables. The problem I have is that I am a very lazy developer, and that I create the getter and setter methods in

Visual Studio 2015 not automatically adding asterisk for multiline comments

阅读更多关于 Visual Studio 2015 not automatically adding asterisk for multiline comments

When typing multi-line comments Visual studio used to add an automatic asterisk to each new line of the comment as I press enter(apparently 2015 does not do this anymore). I really liked this. As of right now though, if I type "/*" and enter, Visual studio does not try to autocomplete it at all. In fact, it even lets me end the comment with "*/" , too, instead of doing it for me. So my question is: is anyone else experiencing this? How do I get the original functionality back, so each new line is automatically prefixed with an asterisk, and closed for me by "*/" ? I already checked and yes, my

Circular Buffer in Simulink

阅读更多关于 Circular Buffer in Simulink

I would like to implement a very huge (10^6 Elements - fixed size) circular buffer in pure Simulink model (no further toolboxes, no S-Function ). At some points I need to read some elements (anywhere, not just begin or end). The following solutions I can not use: "Queue Block" or "Buffer Block" (I have no Signal Processing Toolbox available) "Discrete Delay" ( I need a hugh buffer and will not place 10^6 delays into the model) "Sim Events" (I need to generate code from this model) The "S-Function" I tried not yet, and I am looking for an alternative solution. What further approach do you know?

Generate classes from XSD

阅读更多关于 Generate classes from XSD

You are doing contract first development of web services in a SOA world. After editing an XSD file, what is the best way to automatically (re)generate .net classes from the XSD files? xsd.exe will generate new classes for you. Depending on how Visual Studio is set up, adding xsd.exe to "Properties / build events / post-build events" will force a regeneration every time you do a rebuild. If using .net 1.1 or 2.0, xsd.exe. If using 3.0 or 3.5, svcutil.exe. If you don't mind using non-supported code, LINQ-to-XSD ( http://blogs.msdn.com/xmlteam/archive/2008/02/21/linq-to-xsd-alpha-0-2.aspx ) is

C# to format (indent, align) C# properly

阅读更多关于 C# to format (indent, align) C# properly

We have a code generator that munges the schema of a given database to automate our inhouse n-tier architecture. The output is various C# partial classes, one per file. In the code to munge all the strings, we try and keep on top of the indenting and formatting as much as possible, but invariably when you come to open the file in Visual Studio the formatting is awry. A quick ctrl-k, ctrl-d fixes it, but obviously this reformatting is lost the next time the class is generated. What I'd like to know, is if there's a way I can somehow automatically format the contents of the textfile in the same
