Tool to generate interface implementation by delegation?

阅读更多关于 Tool to generate interface implementation by delegation?

问题 I often need to implement an interface by delegating the implementation to a member of my class. This task is quite tedious because, even though Visual Studio generates stubs for the interface methods, I still have to write the code to delegate the implementation. It doesn't require much thinking, so it could probably be automated by a code generation tool... I'm probably not the first one to think of this, so there must be such a tool already, but I couldn't find anything on Google... Any

How to convert a json to a typescript interface?

阅读更多关于 How to convert a json to a typescript interface?

Given a JSON output of an api: { "id": 13, "name": "horst", "cars": [{ "brand": "VW", "maxSpeed": 120, "isWastingGazoline": true, }] } I would like to define interfaces for typescript: export interface Car { brand: string; maxSpeed: number; isWastingGazoline: boolean; } export interface RaceCarDriver { id: number; name: string; cars: Car[]; } Yet I don't want them to type them manually, I rather have a script generate them for me. How can I convert json into typescript interfaces? I also don't want to use webservices like json2ts . You can write the script using typescript compiler API and its

Can EF4 generate POCO for me, or do I have to write them myself?

阅读更多关于 Can EF4 generate POCO for me, or do I have to write them myself?

问题 I've been playing about with the Entity 4 framework lately and it's pretty nifty. I've setup a class called Customer.cs with some properties like Name, Address etc. I also have a class called StoreEntities.cs which binds these back to the database through DbSet. It works fine and I can pull all my customers from the database. The problem is every tutorial I come across on the internet generates their classes by hand. What I mean is, they all say something like "Now I'm going to make a new

Caching generated classes in Byte Buddy?

阅读更多关于 Caching generated classes in Byte Buddy?

问题 I have been using CGLIB's Enhancer for a while, but considering to switch over to Byte Buddy. It's pretty basic stuff, proxy for up to a few hundred data access interfaces, created on demand. Enhancer enhancer = new Enhancer(); enhancer.setClassLoader(...); enhancer.setSuperclass(...); enhancer.setInterfaces(...); enhancer.setCallback(...); enhancer.create(); CGLIB is caching the generated type to improve performance. What is the recommended approach with Byte Buddy? I want to avoid any

AndroidAnnotations and Unit Testing

阅读更多关于 AndroidAnnotations and Unit Testing

问题 I am using AndroidAnnotations(2.5) in a sample project I am currently working on. Since you can annotate your classes with for example @EActivity , @ViewById , @Click which will all lead to generated compile-time code, I was wondering how one would go about creating unit tests / functional tests for any Android Annotations powered application. I would love to hear some opinions on this matter. Cheers, 回答1: I responded to a similar post here. There are a couple of options available to you. You

How to get String.Format not to parse {0}

阅读更多关于 How to get String.Format not to parse {0}

I am writing a code generation tool that frequently will have lines like StringBuilder sp = new Stringbuilder(); sp.AppendFormat(" public {0}TextColumn()\n", className); sp.AppendLine(" {" sp.AppendLine(" Column = new DataGridViewTextBoxColumn();"); sp.AppendFormat(" Column.DataPropertyName = \"{0}\";\n", columnName); However the issue I am having is when I run in to a line like this. sp.AppendFormat("return String.Format(\"{0} = '{0}'\", cmbList.SelectedValue);", columnName); I want the first {0} to turn in to whatever the value of columnName is but I want the seccond {0} to be left alone so

drools programmatically generate a fact model

阅读更多关于 drools programmatically generate a fact model

I need to generate an enormous fact model using an ontology external to drools. Now, I could certainly write a script/program to pull this off. My approach would be to generate a java bean for each ontology class which contains the appropriate fields, methods, and references to other java objects based on ontological relationships (probably in a map). My question is whether drools has a more elegant way to approach this problem. I figure it must be a common problem that the fact model is derivable from resource available outside of drools, so I'm wondering if maybe drools(or guvnor) has a

Is there a Perl script to implement C++ Class get/set member functions?

阅读更多关于 Is there a Perl script to implement C++ Class get/set member functions?

问题 I was reading this morning the book The Pragmatic Programmer Chapter 3 on Basic Tools every programmer should have and they mentioned Code Generation Tools. They mentioned one Perl script for C++ programs which helped automate the process of implementing the get/set() member functions for private data members. Does anyone know about such a script and where to find it? I've been unable to come up with the right google keywords to find it. 回答1: Although it doesn't directly answer your question,
