wrapper

PHP equivalent for a python decorator?

最后都变了- 提交于 2019-11-29 07:51:32
问题 I want to be able to wrap a PHP function by another function, but leaving its original name/parameter list intact. For instance: function A() { print "inside A()\n"; } function Wrap_A() { print "Calling A()\n"; A(); print "Finished calling A()\n"; } // <--- Do some magic here (effectively "A = Wrap_A") A(); Output: Calling A() inside A() Finished calling A() 回答1: Apparently runkit might help you. Also, you can always do this the OO way. Put the original fun in a class, and the decorator into

Automatically creating a wrapper to implement an interface

喜你入骨 提交于 2019-11-29 07:38:07
问题 I have some classes that don't implement a certain interface but structurally comply to that interface. interface IFoo { void method(); } class Bar { // does not implement IFoo public void method() {...} } Now, I could write a wrapper around those classes that simply delegate to the wrapped class class BarWrapper : IFoo { Bar bar = new Bar(); public void method() { bar.method(); } } But that's lots of tedious work. Can those wrapper classes somehow be generated automatically? Something like:

Are Java wrapper classes really immutable?

倾然丶 夕夏残阳落幕 提交于 2019-11-29 05:32:22
Java Wrapper classes are supposed to be immutable. This means that once an object is being created, e.g., Integer i = new Integer(5); its value cannot be changed. However, doing i = 6; is perfectly valid. So, what does immutability in this context mean? Does this have to do with auto-boxing/unboxing? If so, is there any way to prevent the compiler from doing it? Thank you i is a reference. Your code change the reference i to point to a different, equally immutable, Integer . final Integer i = Integer.valueOf(5); might be more useful. Immutable means that the object state cannot be changed. In

Positioning a “wrapper” div underneath a fixed navigation bar?

I've started work on a brand new site and i've been playing around with designs for a while, however one problem I seem to be having is regarding positioning a navigation bar with a full screen width that is fixed to scroll. Underneath i have created a div called "wrapper" which is set to centre at a width of 980px . Below is code example; <style> #navBar { background: RGB(0, 0, 0); height: 30px; position: fixed; width: 100%; } #wrapper { margin: 0 auto; width: 980px; } </style> <div id="navBar"> </div> <div id="wrapper"> <div style="border: 1px solid RGB(0, 0, 0); float: left; height: 500px;

How to convert a .java or a .jar file into a Linux executable file ( without a .jar extension, which means it's not a .jar file )

若如初见. 提交于 2019-11-29 02:43:07
I have been searching for many similar posts about this but I still can't find my answer. I want to convert a .java program into a Linux executable file, without the .jar extension. How can I do it? I am trying to use Launch4j java wrapper, JWrapper, IzPack, making a .sh, making a .bat, running it using java -jar myFile.jar etc. but none of them worked. Some procedures are complicated and difficult to debug. Is there any straightforward way to convert a .java file or .jar file into a Linux executable file? I need to pass this program as a Linux executable as a whole into another program that

Why doesn't #include <Python.h> work?

可紊 提交于 2019-11-29 01:45:57
I'm trying to run Python modules in C++ using "#include <Python.h>" , however, after setting the "Additional Include Dependencies" of the project to "\include" I get the following error when debuging, LINK : fatal error LNK1104: cannot open file 'python27_d.lib' I read that I should download the development version of Python, but I didn't find a link for that, plus, don't I just need the file 'python27_d.lib' to be copied to the "libs" folder? Please note that I'm using the Anaconda distribution of Python. Thanks in advance! I don't know much about python, but the message indicates that

Java Service Wrapper实践

孤者浪人 提交于 2019-11-29 01:35:58
很久前就使用JAVA写了一个后台服务器,基于MINA框架的。并且一直部署运行于服务器中,当然有一个黑框框。 就正常运行而言,此种运行方式没有任何问题。 但是就这运行期间出现的一些问题: 1,服务器问题重启后,每次都要登录远程将服务器打开,即使我已经配置了开机自启动,但是由于黑框框是基于界面运用的,每次必须要完成系统启动画面之后该黑框框才能启动。所以即使设置成了开机自启动,每次服务器维护重启后,都需要登录一下远程出发系统加载。 2,有个黑框框总显低端些,并且容易不小心被关闭。 基于以上问题,加之以前就对Java Service Wrapper有所涉猎,但并未实践,所以利用一点时间来将服务器打包成WINDOWS NT服务。 关于Java Service Wrapper的介绍在此就不鳌诉了, http://wrapper.tanukisoftware.com/doc/english/download.jsp 本人最简单的了解,就是将JAVA应用打包成标准的WINDOS(当然也包含linux,在此仅以windows为例)服务。 Java Service Wrapper的Standard,Professional版本是需要 license的,通俗的说是要收费,但是Community版本不需要,至于版本之间的区别我想对我影响不大,所以没有深究。就用Community版本吧。 下载下来后解压:

1、下载nginx http://nginx.org/en/download.html 2、解压到本地的某个位置 例如:D:\software\nginx-1.14.2 3、将Nginx设置为Windows服务 需要借助于"Windows Service Wrapper"小工具 下载: http://repo.jenkins-ci.org/releases/com/sun/winsw/winsw/1.18/winsw-1.18-bin.exe 下载该工具后,将其放在 Nginx安装目录下,并重命名为nginx-service.exe,创建配置文件nginx-service.xml(名字要和工具名一样), 创建nginx-service.exe.config(为支持NET 4.0 runtime,默认只支持NET 2.0 runtime) 文件结构如下: nginx-service.xml 内容如下: <service> <id>nginx</id> <name>Nginx Service</name> <description>High Performance Nginx Service</description> <logpath>D:\software\nginx-1.14.2\logs</logpath> <log mode="roll-by-size">

Wrapping C++ for use in C#

情到浓时终转凉″ 提交于 2019-11-28 23:52:26
Ok, basically there is a large C++ project (Recast) that I want to wrap so that I can use it in my C# project. I've been trying to do this for a while now, and this is what I have so far. I'm using C++/CLI to wrap the classes that I need so that I can use them in C#. However, there are a ton of structs and enums that I will also need in my C# project. So how do I wrap these? The basic method I'm using right now is adding dllexport calls to native c++ code, compiling to a dll/lib, adding this lib to my C++/CLI project and importing the c++ headers, then compiling the CLI project into a dll,
