Scala - Dynamic object/class loading

阅读更多关于 Scala - Dynamic object/class loading

In Java, I load external class (in .jar file) by this way: ClassLoader classLoader = new URLClassLoader(new URL[] { new File("module.jar").toURI().toURL()}); Class clazz = classLoader.loadClass("my.class.name"); Object instance = clazz.newInstance(); //check and cast to an interface, then use it if (instance instanceof MyInterface) ... And it works fine. ==================== Now I want to do the same thing in Scala. I have a trait named Module ( Module.scala ): trait Module { def name: String } object Module { lazy val ModuleClassName = "my.module.ExModule" } I write a module extending Module

Is it possible to Load an assembly from the GAC without the FullName?

阅读更多关于 Is it possible to Load an assembly from the GAC without the FullName?

I know how to load an assembly from a filename, and also from the GAC. As My .msi file will put a dll project into the GAC, I'm wondering if it's possible to load it from the GAC unknowing the FullName (I mean just with the assembly name, or even the dll filename), because I have to Load this assembly from another project. Here is a piece of code that allows to do this, and an exemple: string path = GetAssemblyPath("System.DirectoryServices"); Assembly.LoadFrom(path); Note if you need a specific processor architecture, since it supports partial name, you can write this kind of things: // load

How can I use jQuery “load” to perform a GET request with extra parameters?

阅读更多关于 How can I use jQuery “load” to perform a GET request with extra parameters?

I'm reading the jQuery load documentation and it mentions that I can use load to perform a GET request by passing in extra parameters as a string. My current code with my parameters as key/value pair is: $("#output").load( "server_output.html", { year: 2009, country: "Canada" } ); The above works fine but it's a post request. How can I modify the above to perform a GET request while still using load ? According to the documentation you linked: A GET request will be performed by default - but if you pass in any extra parameters in the form of an Object/Map (key/value pairs) then a POST will

Load and execute javascript code SYNCHRONOUSLY

阅读更多关于 Load and execute javascript code SYNCHRONOUSLY

Is there a way to load and execute a javascript file in a synchronous way just like a synchronous XMLHttpRequest? I'm currently using a sync XMLHttpRequest and then eval for this, but debugging that code is very difficult... Thanks for your help! Update I tried this now: test.html <html> <head> <script type="text/javascript"> var s = document.createElement("script"); s.setAttribute("src","script.js"); document.head.appendChild(s); console.log("done"); </script> </head> <body> </body> </html> script.js console.log("Hi"); Output: done Hi So it was not executed synchronously. Any idea to make "Hi

How do I create a progress bar for data loading in R?

阅读更多关于 How do I create a progress bar for data loading in R?

Is it possible to create a progress bar for data loaded into R using load() ? For a data analysis project large matrices are being loaded in R from .RData files, which take several minutes to load. I would like to have a progress bar to monitor how much longer it will be before the data is loaded. R already has nice progress bar functionality integrated, but load() has no hooks for monitoring how much data has been read. If I can't use load directly, is there an indirect way I can create such a progress bar? Perhaps loading the .RData file in chucks and putting them together for R. Does any

JavaScript load a page on button click

阅读更多关于 JavaScript load a page on button click

I am trying to do a very simple task here, I would like to be able to click a button on a page and have it take me to another page. I have tried window.location.href, and a bunch of other things and it does nothing. I have tried different platforms and different browsers, all with the same result. I know that it can call a function but I just cannot get the new page to load. Also this is all in my local file system and both pages live at the same level (but I have also tried to load an external page like www.apple.com). Any thoughts? Thanks Patrick Pranay Rana Simple code to redirect page <!--

R text file and text mining…how to load data

阅读更多关于 R text file and text mining…how to load data

I am using the R package tm and I want to do some text mining. This is one document and is treated as a bag of words. I don't understand the documentation on how to load a text file and to create the necessary objects to start using features such as.... stemDocument(x, language = map_IETF(Language(x))) So assume that this is my doc "this is a test for R load" How do I load the data for text processing and to create the object x? Like @richiemorrisroe I found this poorly documented. Here's how I get my text in to use with the tm package and make the document term matrix: library(tm) #load text

window load inside a document ready?

阅读更多关于 window load inside a document ready?

Sorry if this has been answered before but all searches talk about the differences, not about using the two together, if possible. Simply, can $(window).load.(function() {}) be used INSIDE of $(document).ready.(function() {}) ? I have some things that should be done after the DOM is loaded but then I want to reveal certain elements only after the images have finished loading. The only thing that works in Explorer 8, is putting the $(window).load functions inside of the $(document).ready with everything else. Is this an acceptable practice? I just want to use the most acceptable method to

recover dict from 0-d numpy array

阅读更多关于 recover dict from 0-d numpy array

What happened is that I (by mistake) saved a dictionary with the command numpy.save() (no error messages shown) and now I need to recover the data in the dictionary. When I load it with numpy.load() it has type ( numpy.ndarray ) and is 0-d, so it is not a dictionary any more and I can't access the data in it, 0-d arrays are not index-able so doing something like mydict = numpy.load('mydict') mydict[0]['some_key'] doesn't work. I also tried recdict = dict(mydict) but that didn't work either. Why numpy didn't warn me when I saved the dictionary with numpy.save() ? Is there a way to recover the

Hide soft keyboard on application load

阅读更多关于 Hide soft keyboard on application load

问题 I have an application with an EditText element on the main view. This means that when my application is loaded the soft keyboard appears per default. I would like to be able to hide the keyboard on load, so it does not show until i tap on the EditText view. How do i manage this? 回答1: You can do something easier. Add this to the LinearLayout (or any other layout that is the root): <LinearLayout ... android:focusable="true" android:focusableInTouchMode="true" ... /> 回答2: In your AndroidManifest
