ActionScript 3.0 :: Auto-wiring Dependencies Using Metatags?
Nov 19, 2010
I am working on a system that will allow you to annotate classes with information such as dependencies and the scope of it:
Code:
[Singleton]
[Requires (ClassName1, ClassName2)]
class RenderSystem()
[code]....
This class is a singleton that requires ClassName1:Class, ClassName2:Class. If class 1 or 2 are singletons then it will inject a singleton and if not it will create a new object for it.Memory Manager instantiate method looks like this
Code:
/**
* Instantiate an object
* @param type (Class) The type of object to create
[code]....
For the most part it all works but when mxmc compiles the project it drops unused classes. Since they are dynamically allocated this means that at runtime most of the library isn't there.
I'm using robot legs, I've got a bunch of ServiceResponses that extends a base class and have a dependency on a Parser, IParser. I need to wire in a parser specific to the subclass. Here's an example: ModuleConfigResponse extends SimpleServiceResponse and implements IServiceResponse.
The initial part is easy to wire in the context, here's an example: injector.mapClass(IServiceResponse, ModuleConfigResponse); injector.mapClass(IServiceResponse, SimpleServiceResponse, "roomconfig"); ..etc
Each Response uses a parser that is used by the baseclass: injector.mapValue(IParser, ModuleConfigParser, "moduleconfig"); injector.mapValue(IParser, RoomConfigParser, "roomconfig");
The question is how to tie these together. The base class could have: [Inject] public var parser : IParser
But I can't define the type ahead of time. Im wondering if there a nice way of wiring this in the context. For the moment I've decided to wire this up by instanciating responses in a ResponseFactory instead so that I pay pass the parser manually in the constructor. injector.mapValue(IParser, ModuleConfigParser, "moduleconfig");
I'm starting with Parsley and cannot manage to make the autowire working. My configuration is based on flex 4.5 and parsley 3.0.0. My application contains the folowing bootrap :
[code]....
The workaround is quite heavy as it requires adding in all my views the proprietary tags. what is wrong with my configuration?
can I programatically detect if a var has been flagged with the built-in metatages such as [Transient] or [Bindable]?
rolling my own metatags? I know the possibility for them exists, but all I can find is either outdated or very vague.
For example, I'd love to make a tag that specifies a var as being [WriteOnce] or can only be modified if the user has a certain [SecurityAccess] or is only set when launched in my [Sandbox].
I'd like to add a derived property to flex:[code]However, derived won't update when I change a or b.Is there a better (faster) way to make derived update than giving a and b setter methods which invalidate it?added keyword "get".This makes more sense now, I hope.
I have two Flex libraries that reference each other. Both use link type "External", and I manually load then with the Loader class.I'm getting the error "A cycle was detected in the build path of project: foo".
I have several Flex applications in a project, and I would like to know if there's a way to get a list of the classes (and ideally, other assets) that are being compiled into each one. I want an easy way of making sure I've kept things separate and there aren't unnecessary dependencies. Any ideas? I'm running Flash Builder 4.
I'm trying to understand how packages and dependencies work with Adobe Flash Builder 4. I've copied an example here and put it in a .as file called DependencyGraph. However I get the error message: A file found in a source-path must have the same package structure '', as the definition's package, 'DependencyGraph'. I understand that the original file has a package name called package flare.apps. What should I change to enable this to run?
I'm trying to use the MovieClipLoader class to load external swfs into my main movie. A problem occurs when the external swf relies on or loads other external files. The external swf acts as if it's running in the same directory as the main swf and expects files to be located relative to that.
For example: main_movie/main.swf other_path/external.swf
[Code]......
This seems to be similar to having the base parameter set improperly in the html, but I haven't been able to find a way to set this when loading an swf dynamically with MovieClipLoader.
I'm looking for a way to collect the file dependencies from Flex ActionScript and MXML files. I was hoping that mxmlc could spit them out (like gcc's -M option), but its option list doesn't seem to have anything relevant. I could write a parser, but would prefer not to reinvent the wheel if it has already been done, particularly given the two very different languages involved. In particular, star imports and in-package implicit imports could be troublesome.
I have a large Flex project with two Applications in it. A lot of code is shared between these Applications. However, the smaller of the Applications does not require much of the code that the larger one does. I'm trying to ensure that code that isn't required by the smaller application isn't getting compiled into it.
I trying to integrate Flex with Grails through BlazeDS but I am stuck with the very first step i.e installing BlazeDS plugin ... it fails everytime i try to install. Following is the complete stacktrace
Resolving plugin JAR dependencies ... Warning module not found: com.adobe.flex#flex-messaging-opt;4.0.0.14931.1 grailsHome: tried D:PlatformsGrailsgrails-1.3.7lib/flex-messaging-opt-4.0.0.14931.1.xml [Code] .....
So I have a project comprised of multiple modules and I'm trying to work out the best way to compile, with minimal code duplication.
I have a core Framework SWF and a number of sub applications which are independent of core. In addition I have a series of common library SWCS which core and subapps are dependant on.
I'm not sure the best way to compile this project so that each module does not need to include the libraries as this would duplicate code. Would love some advice!
I started out with using external-library-path for compilation, but something is going to have to include the common libraries.
I'm used to building applications using pure AS3. I always pass dependencies into the constructor of classes I make, but this method seems to not work out well for Flex MXML views. It seems like I should define setters on the MXML class, which map to attributes in the tag/class instantiation. But using this method I cannot specify which properties are required and in what order I expect them etc. What is the preferred method to give a Flex view it's dependencies?
Can someone tell me if its possible to create relative as opposed to absolute paths to swcs in module dependencies for Flex or actionscript modules?In Flex Builder i would simply edit the swc path as'../lib/.swc..But there doesn't seem to be a way to edit the path in IntelliJ once you've defined it.
I'm making an interactive film. At certain points within the film, the viewer has the ability to select from a few options that will direct them to an external video clip (they are flashback scenes). The main story pauses when the user selects a flashback scene and I'm clear on how to achieve this.
However, my issue is that once the flashback scene ends and the external video closes, I'm not sure how the main story will resume. Is it possible for it to auto-play (resume) in some way? My last resort would be to have the viewer select a play button - this is only because I do not want a break in the narrative and want to limit the amount of clicks the viewer has to make.
I want to make and burn some CD's that are composed mostly of Flash. They are interactive CD's and i want them to open and function on both PC and Mac simply by inserting them. The CD's are for younger children and i would want to try and not have the user track down and install Flash Player everytime.
in the actions panel, it auto imports classes as your typeing. but not when typing in an .as file. however you don't need to import classes if you place code on the main timeline with the actions panel...
I have the same flash file uploaded to two servers. It seems to work perfectly fine on one (IE, Firefox and Chrome) but on the other it works only on Firefox, not even chrome.
The thing is I guess the flash file does load, but until I right click and click play, the file does not start playing.
I create a small animation with ActionScript (basically fadeIn/fadeOut at different interval of different images). When I view in FlashPlayer directly it work when I view in browsers (any) I need to "click" inside the application for the fadeIn to start.
In my application I use this : stage.addEventListener(Event.ACTIVATE, launch);so I guessed it was caused because by defautl the application is not activated, my question is how can I make the animation start at loading without needing to click on it?
I've been experiencing a supposed fault with CS3's autoformatting.It completely ignores my selected option of putting spaces around operators, and when assigning variables a class:
Code: var theText = new TextField ();
it turns it into
Code: var theText=new TextField ;
erasing the parenthesis... this is definitely not normal.When I delete the spaces that it creates, then autoformat it, it recreates the two spaces...
I am putting together a flash presentation to hand out on cd. I have seen some flash presentation cd's do the auto-run thing. How is this accomplished? Actually not sure if this is AS or not. But if anyone has a clue, snippet, fla, tutorial even some ancient writings on this.
would like to know if there is any way to create and call an action from outside of flash that will resize the swf to dimensions I set?for example if I make a banner that is 300x250, and I want that exact banner in 336x280, instead of entering each swf source and resizing it (I have many banners) I would like to make it easier...
please take a look at [URL] The flash graphic is supposed to auto-resize to the page size but it does not. If I take the same code and put it in an "ordinary" webpage it works fine - look at [URL] What I had hoped to acheive is the effect in this page where the flash movie resizes to match the size of the browser window. I am using the script AC_RunActiveContent.js and calling it from the webpage with the height and width attributes set to 100% - it seems to be sizing the flash at 100x100 instead.....
I am trying to get the background and main part of my website to scale up to the full size of the web browser when it is resized. i have found an example, and have been searching for hours trying to find a solution.when you resize the browser it fits, i would like to know how i could achieve this.
