circular-dependency

问题 I've dug myself into quite a hole here. I'm working on a Python/Kivy app in PyDev. The app runs off of many systems (about 10), so I shoved them into an engine to handle everything. For ease of access, I grab the engine via (the worst) singletons main.py #main.py from code import engine class MyApp(App): def build(self): engine.GetInstance().Initialize() if __name__ == '__main__': MyApp().run() engine.py #engine.py from code import system1 from code import system2 gEngineInstance = None def

问题 I have added another project "xml" to my project "synchronise". So program.cs (in the xml project) runs the getDetails(), which runs the FectchDetails() in the synchronise project and returns the result as an object to the xml/getDetails(). If an error occurs in the Synchronise/FecthDetails() I want to re run the xml/getDetails(). Ive tried xml.getDetails, but it is saying it doesnt exist, because its not reference to the project so I try to add the xml project to the synchroinse but its

问题 This question already has answers here : How to handle circular dependencies with RequireJS/AMD? (7 answers) Closed 2 years ago . Given: StringPreconditions extends ObjectPreconditions ObjectPreconditions depends on StringPreconditions (one of its methods returns the subclass) Preconditions is a gatekeeper to ObjectPreconditions and StringPreconditions (making sure they both load before returning an instance) User depends on Preconditions I have this code: define(["ObjectPreconditions"],

问题 I am currently facing a very disturbing problem: interface IStateSpace<Position, Value> where Position : IPosition // <-- Problem starts here where Value : IValue // <-- and here as I don't { // know how to get away this // circular dependency! // Notice how I should be // defining generics parameters // here but I can't! Value GetStateAt(Position position); void SetStateAt(Position position, State state); } As you'll down here, both IPosition , IValue and IState depend on each other. How am

问题 I think I have a cyclic dependency issue and have no idea how to solve it.... To be as short as possible: I am coding something like a html parser. I have a main.cpp file and two header files Parser.h and Form.h. These header files hold the whole definitions... (I'm too lazy to make the corresponding .cpp files... Form.h looks like this: //... standard includes like iostream.... #ifndef Form_h_included #define Form_h_included #include "Parser.h" class Form { public: void parse (stringstream&

问题 Related to a previous question, I have now the following one: In the next scenery: class B; class A { // stuff, methods and so on B b; }; class B { // stuff, methods and so on A a; }; Here we have a circular dependence between A and B , but this code is ill-formed since B is an incomplete type. A solution is to change B by a pointer of B by means of a smart pointers for example. But adding pointer add complexity and resources spending unnecesarily since you don't need a pointer! In the

问题 I seem to be having circular dependency problems with using UserType inside AdType. This is my UserType file: UserType This is my AdType file: AdType If I try to use the code below I get the error "Ad.user field type must be Output Type but got: undefined" even tho I imported the UserType properly. import { UserType } from '../User/user.graphql.model' import { UserSchema } from '../User/user.mongoose.model' const user = { type: UserType, resolve(parentValue, args) { return UserSchema.findById

问题 Based on feedback I got from this question, I'm interested in using Lazy C++ on my OSX laptop. The Lazy C++ webpage has binaries for Linux and Windows available, but nothing for OSX. There's also a link to download for the Lazy C++ source, but it requires a lzz binary as part of the build process. This creates a situation where I need an lzz binary in order to get an lzz binary. How can I build lzz on my laptop without an lzz binary? Do I need to do part of the build on a Linux or Windows

问题 I'm trying to implement circular dependency between my AppDelegate and my ViewController to call methods from my AppDelegate to my ViewController but it's not working. See my code as follow: AppDelegate.h: @class ViewController; @interface AppDelegate : UIResponder <UIApplicationDelegate> @property (strong,nonatomic) ViewController *mainView; @end; AppDelegate.m: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { return YES; } -

问题 I would like to use cffi (or even ctypes if I must) to access a C ABI from Python 3 on Linux. The API is implemented by a number of .so files (let's call them libA.so , libB.so and libC.so ), such that libA contains the main exported functions, and the other libs provide support for libA . Now, libA depends on libB and libB depends on libC . However, there's a problem. There's a global array defined by libA that libC expects to be present. So libC actually depends on libA - a circular
