Calling Objective-C parent from C++ object

倾然丶 夕夏残阳落幕 提交于 2019-12-11 04:29:21
问题 Creating Audio Unit Extensions on iOS requires mixing of C++ and Objective-C classes. As a result I now have an Objective-C object with a C++ object as one of its variables. I would like the C++ child object to be able to notify its Objective-C parent/owner of certain state changes. In pseudo-code: void cppChildObject::callMom() { objectiveCParent::notificationMethod(); } Is this possible in an elegant way? 回答1: It depends on how you define elegant... This is possible in a fairly elegant way

Scala : get mixin interfaces at runtime

早过忘川 提交于 2019-12-10 16:00:05
问题 I need to get all the interfaces at runtime from a given Class (all loaded in a ClassLoader). For instance, if a class has been declared this way : trait B trait C trait D class A extends B with C with D I want to get this information at runtime : A depends on B and C and D . The java getInterfaces() (or the interfaces() from the clapper library) methods gives only the first dependency, namely: A depends on B . Is there a way to achieve that ? I guess by reflection but I don't know how ? 回答1:

Can you mix the JVM languages? ie: Groovy & Clojure

China☆狼群 提交于 2019-12-09 09:23:17
问题 I understand that you can easily mix groovy&java, clojure&java, whateverJvmLang&java. Does this also mean I can have clojure and groovy code interact as well? If I use Grails or jRoR, can I also make use of clojure in that environment? 回答1: As long as the languages in question actually produce Java classes (that is: classes that are known to the Java platform, not necessarily written in the Java language), then yes: they can easily interact with each other. At least for Groovy I know that it

问题 I would like to mix MP3 files with Delphi 2010. Is this possible? Does anyone know of a component (set) I could use to get this done? Or maybe a runtime library? Any tips from someone with experience mixing MP3 files? 回答1: I use newAc: http://symmetrica.net/newac/ it has a soundmixer component and supports mp3 inputs. Cheers! 回答2: FFmpeg has pascal headers, which apparently you can use from delphi: http://www.iversenit.dk/dev/ffmpeg-headers/ This should allow you to load mp3s or any other

How to mix sound files of different format using FFMPEG?

不打扰是莪最后的温柔 提交于 2019-12-06 08:34:39
I need to mix audio files of different types into a single output file through code in my iPad app. For example, I need to merge a .m4a file with .mp3 or .wav or any other format file. The resulting output file should be of .m4a type. I have compiled FFMPEG for iOS with the link: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html Now, I am not able to understand in which direction to proceed? This is more of a suggestion than an answer. I don't have any experience with obj-c, though I have worked with audio formats in other languages. Unless you find some library that

I have several sound objects in flash, I would like to mix different points in these sound files to create a single masterpiece and save it as an mp3. I've seen various "mixer" applications online and would like to know what area(s) to look at to be able to do this myself. To create the music or whatever you're trying to create, you'll have to Import your wav and mp3 files into your library and drag them onto the movie area to add them to your timeline. Use multiple layers to help organize them. To test your song out you can hit Enter to run from whatever frame your on forward to the end. Don

Best way to access Java classes from C++? (better than using JNI directly)

时光怂恿深爱的人放手 提交于 2019-12-05 12:19:18
I have to integrate a large Java library in a quite large C++ application. A solution is to use JNI but this requires to hand code all the classes. Python has, for example, a wonderful solution with JPype ( http://jpype.sourceforge.net/ ) that automatizes the process (although the same solution cannot be applied to C++ due to C++ and Python different natures). Thanks, Das SWIG is a tool that lets you auto-generate bindings from one language to another. It supports C++ and Java and a dozen other languages. Seems that my question was not clear enough. Maybe the confusion comes from JNI that
