circular-dependency

问题 I have been try out many suggestions I found googling for circular dependency in node and requirejs. Unfortunately, I'm not getting it to work. The try which is closed to a solution (I think) is below: // run.js var requirejs = require('requirejs'); requirejs.config({ baseUrl: __dirname, nodeRequire: require }); requirejs(['A'], function(A) { var a = new A.Go(); console.log(a.toon()) }); // A.js define(['B', 'exports'], function(B, exports) { exports.Go = function() { var b = new require('B')

问题 Problem How can I avoid the following error from Lua 5.1 when attempting to do a circular require? $ lua main.lua lua: ./bar.lua:1: loop or previous error loading module 'foo' stack traceback: [C]: in function 'require' ./bar.lua:1: in main chunk [C]: in function 'require' ./foo.lua:1: in main chunk [C]: in function 'require' main.lua:1: in main chunk [C]: ? File Structure main.lua require "foo" require "bar" print (Foo.getName()) print (Bar.getName()) foo.lua require 'bar' Foo = {} Foo.name

问题 Say I have this table structure: Client ----------- ClientId int not null (identity) CurrentDemographicId int null (FK to ClientDemographic) OtherClientFields varchar(100) null ClientDemographic ------------------ ClientDemographicId int not null (identity) ClientId int not null (FK to Client) OtherClientDemographicFields varchar(100) null The idea is that Client (in EF) will have a ClientDemographics list and a CurrentDemographic property. The problem is when I setup the object structure and

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed last year . What is a good way of dealing with objects and having them talk to each other? Up until now all my games hobby/student have been small so this problem was generally solved in a rather ugly way, which lead to tight integration and circular dependencies. Which was fine for the

问题 Is it possible to avoid circular dependency in the following header files without turning data member b1 in class A to a pointer/reference, and without relaxing the inline function requirement in class B ? A.h: #ifndef A_H #define A_H #include <B.h> // Required, as data member b1 is not a pointer/reference class A { public: B b1; // I want to keep this as as it is. int m_a; }; #endif B.h: #ifndef B_H #define B_H #include <A.h> // Required, as f() calls a member function of class A class B {

问题 I've made the example in Java but I think (not tested) that it works in other (all?) languages. You have 2 files. First, M.java : public class MType { XType x; MType() {x = null;} } Second, another file (in the same directory), XType.java : public class XType { MType m; public XType(MType m) {this.m = m;} } Ok it's bad programming, but if you run javac XType it compiles: compiles even MType because XType needs it. But ... MType needs XType ... how does that work? How does the compiler know

问题 What is the best way to resolve the following circular dependency in typedef-ing these structs? Note the C language tag - I'm looking for a solution in standard gcc C. typedef struct { char* name; int age; int lefthanded; People* friends; } Person; typedef struct { int count; int max; Person* data; } People; 回答1: Forward-declare one of the structs: struct people; typedef struct { /* same as before */ struct people* friends; } Person; typedef struct people { /* same as before */ } People; 回答2:

问题 So, I'm having a big issue with circular dependency. My Square.h and Circle.h classes both inherit Shape.h, and use double dispatch in order to try and detect collision between the two. My classes are currently setup in the following sort of fashion Shape.h class Shape { public: virtual bool detectCollision(Shape* obj) = 0; virtual bool detectCollision(Square* obj) = 0; virtual bool detectCollision(Circle* obj) = 0; Square.h #include "shape.h" class Square : public Shape { public: bool
