I am working on rewriting my fluent interface for my IoC class library, and when I refactored some code in order to share some common functionality through a base class, I hit upon a snag.
It sounds silly, but I can\'t get it. Why can the expression [] == [] be typed at all? More specifically, which type (in class Eq) is inferred to the type of list elements?
I was just pottering about with Tony Morris\' excellent exercise on catamorphisms, when I was pondering what was happening in the following situation...
I have the following haskell code: fac n = product [1..n] taylor3s w0 f f\' f\'\' t h = w1 : taylor3s w1 f f\' f\'\' (t+h) h
I am using the Entity Framework, ASP.NET and C#3.5 I borrowed the following code to make sorting possible using a sortExpression from a GridView instead of the property of an entity:
foldr:: (a -> b -> b) -> b -> [a] -> b map :: (a -> b) -> [a] -> [b] mys :: a -> a
I would like to write an object generator for a templated RAII class -- basically a function template to construct an object using type deduction of parameters so the types don\'t have to be specified
I was playing around the other day with making a class to handle some arithmetic operations (yes, I know numeric is coming out in 2.8) and found myself wondering how to simplify the following:
I have a problem using a parameterized class as the key-type of a Map. First create the parameterized class:
I have the following simple Java code: package testj; import java.util.*; public class Query<T> { private static List<Object> l = Arrays.<Object>asList(1, \"Hello\", 3.0);
