Is there a way to implicitly add methods in scala object?
Upd:
For example, Unfiltered scala library have singleton object Body which contains methods Body.string(req: HttpRequest) and Body.bytes(req: HttpRequest) for read body from http request. So, I want read body in my domain objects, like Body.cars(req:HttpRequest).
import scala.language.implicitConversions
object ObjA
object ObjB {
def x = 1
}
object Main {
implicit def fromObjA(objA: ObjA.type) = ObjB
def main(args: Array[String]): Unit = {
println(ObjA.x)
}
}
What do you mean by implicitly adding methods? Does this code snipper answer your question:
implicit def toFunkyString(s: String) = new {
def reverseUpper = s.reverse.toUpperCase
}
"Foo".reverseUpper //yields 'OOF'
toFunkyString("Foo").reverseUpper //explicit invocation
"Foo" is a class instance, what I mean is adding methods in singleton object, something like Math.myMethod(1). Is it all the same?
