Differences between ServletResponse and HttpServletResponseWrapper?

a 夏天 提交于 2019-11-26 20:00:47
问题 I am new to servlet and reading some text about filters and wrappers. I can understand filters but got confused about wrappers. In the book, the author gives an example: In case no wrapper: public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { String name = request.getParameter("name").trim(); try { chain.doFilter(request, response); PrintWriter out = response.getWriter(); if (name.length() == 0) { out.println("Some

How to test internal class library?

假如想象 提交于 2019-11-26 19:40:09
问题 I would like to write a class library which creates for me a complex object but should only be exposed as little as possible. I want it to be included into other projects and there I only have one call to this library which e.g. returns me an object of a internally created class. I don't want to allow others to create these objects explicitly, but still I want to create a test project for this class library. For example: var result = Manager.Instance.Create(definition) This should be the only

Simple PDO wrapper

独自空忆成欢 提交于 2019-11-26 19:13:07
问题 My web application currently has do execute simple queries: simple CRUD operations, counting,... A few months ago, someone recommended me here to write a simple PDO wrapper for this (to avoid writing try/catch, prepare(), execute(), etc. each time a query should be executed). This example method was shown (I've made some changes so I could use it in my own project): public function execute() { $args = func_get_args(); $query = array_shift($args); $result = false; try { $res = $this->pdo-

How to decorate all functions of a class without typing it over and over for each method? [duplicate]

我与影子孤独终老i 提交于 2019-11-26 16:01:52
This question already has an answer here: Attaching a decorator to all functions within a class 6 answers Lets say my class has many methods, and I want to apply my decorator on each one of them, later when I add new methods, I want the same decorator to be applied, but I dont want to write @mydecorator above the method declaration all the time? If I look into __call__ is that the right way to go? IMPORTANT: the example below appears to be solving a different problem than the original question asked about. EDIT: Id like to show this way, which is a similar solution to my problem for anyobody

Tesseract 3 (OCR) - .NET Wrapper

人盡茶涼 提交于 2019-11-26 15:47:23
问题 http://code.google.com/p/tesseractdotnet/ I am having a problem getting Tesseract to work in my Visual Studio 2010 projects. I have tried console and winforms and both have the same outcome. I have come across a dll by someone else who claims to have it working in VS2010 : http://code.google.com/p/tesseractdotnet/issues/detail?id=1 I am adding a reference to the dll which can be found in the attached to post 64 from the website above. Every time I build my project I get an

How != and == operators work on Integers in Java? [duplicate]

徘徊边缘 提交于 2019-11-26 15:29:37
This question already has an answer here: Why is 128==128 false but 127==127 is true when comparing Integer wrappers in Java? 6 answers The following code seemed really confusing to me since it provided two different outputs.The code was tested on jdk 1.7. public class NotEq { public static void main(String[] args) { ver1(); System.out.println(); ver2(); } public static void ver1() { Integer a = 128; Integer b = 128; if (a == b) { System.out.println("Equal Object"); } if (a != b) { System.out.println("Different objects"); } if (a.equals(b)) { System.out.println("Meaningfully equal."); } }

/LinkResource in Visual Studio 2010

非 Y 不嫁゛ 提交于 2019-11-26 14:46:30
问题 /linkresource is a csc option that allows to link an assembly to its unmanaged dependencies. When the managed assembly is added to the GAC, the dependencies are placed in the same folder. This is how all the .NET wrappers should be installed... There is very little information on how to do this in Visual Studio. There is no official answer, just people that hacked a solution. For example http://www.netframeworkdev.com/msbuild/msbuild-linkresource-nonassembly-external-file-beforecompile-24358

How to wrap every method of a class? [duplicate]

萝らか妹 提交于 2019-11-26 13:10:09
问题 This question already has answers here : Applying a decorator to every method in a class? (4 answers) Closed last month . I'd like to wrap every method of a particular class in python, and I'd like to do so by editing the code of the class minimally. How should I go about this? 回答1: An elegant way to do it is described in Michael Foord's Voidspace blog in an entry about what metaclasses are and how to use them in the section titled A Method Decorating Metaclass. Simplifying it slightly and

Using == operator in Java to compare wrapper objects

爱⌒轻易说出口 提交于 2019-11-26 11:48:00
I'm reading SCJP Java 6 by Kathy Sierra and Bert Bates and this book is confusing me so much. On page 245 they state that the following code below. Integer i1 = 1000; Integer i2 = 1000; if(i1 != i2) System.out.println("different objects"); //Prints output different objects Then on the very next page they have the following code Integer i3 = 10; Integer i4 = 10; if(i3 == i4) System.out.println("same objects"); //Prints output same objects I'm so confused! When I try this out on my own it seems that you cannot use the == to compare the same way you would use equals() method. Using the == always

Is there any LAME C++ wrapper\simplifier (working on Linux Mac and Win from pure code)?

余生颓废 提交于 2019-11-26 10:32:13
问题 I want to create simple pcm to mp3 C++ project. I want it to use LAME. I love LAME but it\'s really big. so I need some kind of OpenSource working from pure code with pure lame code workflow simplifier. So to say I give it File with PCM and DEST file. Call something like: LameSimple.ToMP3(file with PCM, File with MP3 , 44100, 16, MP3, VBR); ore such thing in 4 - 5 lines (examples of course should exist) and I have vhat I needed It should be light, simple, powerfool, opensource, crossplatform.
