Where can I find documentation for Scala's delayed function calls?
- by Geo
I saw a delayed example in David Pollak's "Beginning Scala". I tried to adapt that, by trial and error. Here's what I have:
def sayhello() = {
println("hello")
}
def delaying(t: => Unit):Unit = {
println("before call")
t
println("after call")
}
delaying(sayhello())
How would you delay a function/method that takes parameters? Why can't I use parantheses when I call t? Where can I find more documentation on delaying functions?
