circular-reference

I had the problem, to serialize my Java objects through Google GSON, because of several circular references. All my tries ended up in a StackOverflowException, because GSON is not able to handle those circular references. As a solution, I found following GraphAdapterBuilder : http://code.google.com/p/google-gson/source/browse/trunk/extras/src/main/java/com/google/gson/graph/GraphAdapterBuilder.java?r=1170 Example: https://groups.google.com/forum/#!topic/google-gson/z2Ax5T1kb2M { "0x1": { "name": "Google", "employees": [ "0x2", "0x3" ] }, "0x2": { "name": "Jesse", "company": "0x1" }, "0x3": {

I wrote this simple Prolog program. man(socrates). mortal(X) :- man(X). immortal(X) :- immortal(X). I asked it the usual questions, such as whether Socrates is a man or if Socrates is a mortal. ?- man(socrates). true. //we know for a fact that Socrates is a man ?- mortal(socrates). true. //and it can logically be inferred that Socrates is mortal ?- immortal(socrates). //but we can't seem to figure out if he's immortal It crashed because of the recursive definition of immortal . Circular references also make it crash or error with Out of stack space. It seems to me that, at least in this case,

By using graphql-js, I need to create graphql schema dynamically by iterating over array of some data, for example: [{ name: 'author', fields: [{ field: 'name' }, { field: 'books', reference: 'book' }] }, { name: 'book', fields: [{ field: 'title' }, { field: 'author', reference: 'author' }] }] The problem is circular references. When I'm creating AuthorType I need BookType to be already created and vise versa. So resulting schema should look like: type Author : Object { id: ID! name: String, books: [Book] } type Book : Object { id: ID! title: String author: Author } How can I solve this?

I am using the BeforSignup in the AfterSignup unit in order to be able to call the email variable from within AfterSignup code, finally i enbcountred a problem because i want to make a button which opens the AfterSignup window using the code : AfterSignup.Show; But the problem is that i am obliged to add the AfterSignup unit to the uses list of BeforeSignup and that is exactly what i can't do because i am alreadey using BeforeSignup to AfterSignup unit. i receive an error saying, a reference of circular unit. The easy solution would be to add unitA in the uses clause of the interface section
