Suppose I have the code:
class A(implicit s:String = "foo"){println(s)}
object X {
implicit val s1 = "hello"
}
object Y {
import X._
// do something with X
implicit val s2 = "hi"
val a = new A
}
I get the error:
<console>:14: error: ambiguous implicit values:
both value s2 in object Y of type => String
and value s1 in object X of type => String
match expected type String
val a = new A
Is there any way I can tell Scala to use the value s2
in Y
?
(if I rename s2
to s1
, it works as expected but that is not what I want).
Another solution is to not do import X._
, again something I'm trying to avoid.
The implicit parameter in Java is the object that the method belongs to. It's passed by specifying the reference or variable of the object before the name of the method. An implicit parameter is opposite to an explicit parameter, which is passed when specifying the parameter in the parenthesis of a method call.
Implicit parameters are the parameters that are passed to a function with implicit keyword in Scala, which means the values will be taken from the context in which they are called.
Another thing you can do is to import everything but s1
: import X.{s1 => _, _}
.
