Consider the following two classes, both of them have a parseFrom function.
class X {}
object X {
def parseFrom(b: Array[Byte]): String = "Hello"
}
class Y {}
object Y {
def parseFrom(b: Array[Byte]): String = "HelloY"
}
I want to write a macro:
getParseFrom[X] that will return the X.parseFrom function.
This is what I have so far:
import scala.reflect.macros.whitebox.Context
def getParseFromImpl[T: c.WeakTypeTag](c: Context): c.Tree = {
import c.universe._
val tpe = weakTypeOf[T]
q"""
$tpe.parseFrom(_)
"""
}
def getParseFrom[T]: Array[Byte] => String = macro getParseFromImpl[T]
Is this possible with scala macros in scala 2.12?
