circular-reference

I'm using the MVC framework Symfony , and it seems a lot of the built-in objects I want to debug have circular references. This makes it impossible to print the variables with print_r() or var_dump() (since they follow circular references ad infinitum or until the process runs out of memory, whichever comes first). Instead of writing my own print_r clone with some intelligence, are there better alternatives out there? I only want to be able to print a variable (object, array or scalar), either to a log file, http header or the web page itself. Edit: to clarify what the problem is, try this

Is there an existing javascript library which will deserialize Json.Net with reference loop handling? { "$id": "1", "AppViewColumns": [ { "$id": "2", "AppView": {"$ref":"1"}, "ColumnID": 1, } ] } this should deserialize to an object with a reference loop between the object in the array and the outer object The answers given almost worked for me, but the latest version of MVC, JSON.Net, and DNX uses "$ref" and "$id", and they may be out of order. So I've modified user2864740's answer. I should note that this code does not handle array references, which are also possible. function

I'm using Automapper to map my NHibernate proxy objects (DTO) to my CSLA business objects I'm using Fluent NHibernate to create the mappings - this is working fine The problem I have is that the Order has a collection of OrderLines and each of these has a reference to Order . public class OrderMapping : ClassMap<OrderDTO> { public OrderMapping() { // Standard properties Id(x => x.OrderId); Map(x => x.OrderDate); Map(x => x.Address); HasMany<OrderLineDTO>(x => x.OrderLines).KeyColumn("OrderId").Inverse(); Table("`Order`"); } } public class OrderDTO { // Standard properties public virtual int

I'd like to have struct members that know their parent. This is approximately what I'm trying to do: struct Parent<'me> { children: Vec<Child<'me>>, } struct Child<'me> { parent: &'me Parent<'me>, i: i32, } fn main() { let mut p = Parent { children: vec![] }; let c1 = Child { parent: &p, i: 1 }; p.children.push(c1); } I tried to appease the compiler with lifetimes without completely understanding what I was doing. Here's the error message I'm stuck on: error[E0502]: cannot borrow `p.children` as mutable because `p` is also borrowed as immutable --> src/main.rs:13:5 | 12 | let c1 = Child {

I'm having and issue with the Circular reference. I have Rest Webservices which returns objects to the front end, the issue is when I try to return objects that have several references so as the result I get an infinite response, which generate java.lang.IllegalStateException: Cannot call sendError() after the response has been committed The objects are generated automatically by Hibernate Code Generation and I need to have the circular reference in the backend, I've just need to remove it before send the information to the frontend using Jackson. The controller method header is:
