The pimp-my-library pattern allows me to seemingly add a method to a class by making available an implicit conversion from that class t开发者_如何学Goo one that implements the method.
I am running into a problem when trying to implicitly convert one of my dynamic types. There are two assemblies with definitions similar to the following:
Is there a way to make this work (Scala 2.8.1): class A class B def f(implicit b: B) {} implicit val a = new A
Assume you want to add some methods to all Iterables. That can look like this: import collection.generic.CanBuildFrom
I need to convert between these two classes, and want to maintain DRY but not violate the Single Responsibility Pattern...
Given: public struct Id { readonly int m_id; public Id(int id) { m_id = id; } public static implicit operator int(Id id)
If I define a print function that only takes numbers as: def print[T <% Number](value:T) {} print: [T](value: T)(implicit evidence$1: (T) => java.lang.Number)Unit
Let\'s assume I want to create a trait that I can mix in into any Traversable[T]. In the end, I want to be able to say things like:
A pointer to non-const data can be implicitly converted to a pointer to const data of the same type: int*x = NULL;
I\'d like to add implicit conversions to Java classes generated by a modeling tool. So I want to add them to the companion object of those classes, so that the compiler automatically finds them. But I
