From f9a5880bf82b71174eb3dbd6b67646bbc27a975a Mon Sep 17 00:00:00 2001 From: Eugene Burmako Date: Sun, 16 Mar 2014 10:18:26 +0100 Subject: introduces Mirror.typeOf I just realized that our tag-based shortcuts were incomplete, because they only work with root mirrors (doing just u.typeTag[T].tpe means that the type is going to be resolved in u.rootMirror because that's the default). This commit fixes this oversight. I'm hoping for 2.11.0-RC3, but also feel free to reschedule to 2.12.0-M1 if it becomes clear that RC3 isn't happening. --- test/files/run/mirror_symbolof_x.check | 13 ++++++++++ test/files/run/mirror_symbolof_x.scala | 43 ++++++++++++++++++++++++++++++++++ 2 files changed, 56 insertions(+) create mode 100644 test/files/run/mirror_symbolof_x.check create mode 100644 test/files/run/mirror_symbolof_x.scala (limited to 'test/files/run') diff --git a/test/files/run/mirror_symbolof_x.check b/test/files/run/mirror_symbolof_x.check new file mode 100644 index 0000000000..cc9cad7a13 --- /dev/null +++ b/test/files/run/mirror_symbolof_x.check @@ -0,0 +1,13 @@ +class Int +object C +type T +type Id +class Nothing +class Null +class Int +object C +type T +type Id +class Nothing +class Null +exception: class C not found. diff --git a/test/files/run/mirror_symbolof_x.scala b/test/files/run/mirror_symbolof_x.scala new file mode 100644 index 0000000000..8fec301f56 --- /dev/null +++ b/test/files/run/mirror_symbolof_x.scala @@ -0,0 +1,43 @@ +import scala.reflect.runtime.universe._ +import scala.reflect.runtime.{universe => ru} +import scala.reflect.runtime.{currentMirror => cm} +import scala.reflect.api.Mirror + +class C +object C + +object Test extends App { + object test1 { + val m = cm + type T = Int + type Id[X] = X + println(m.symbolOf[Int]: ru.TypeSymbol) + println(m.symbolOf[C.type]: ru.TypeSymbol) + println(m.symbolOf[T]: ru.TypeSymbol) + println(m.symbolOf[Id[_]]: ru.TypeSymbol) + println(m.symbolOf[Nothing]: ru.TypeSymbol) + println(m.symbolOf[Null]: ru.TypeSymbol) + } + + object test2 { + val m: Mirror[ru.type] = cm + type T = Int + type Id[X] = X + println(m.symbolOf[Int]: ru.TypeSymbol) + println(m.symbolOf[C.type]: ru.TypeSymbol) + println(m.symbolOf[T]: ru.TypeSymbol) + println(m.symbolOf[Id[_]]: ru.TypeSymbol) + println(m.symbolOf[Nothing]: ru.TypeSymbol) + println(m.symbolOf[Null]: ru.TypeSymbol) + } + + object test3 { + val m = ru.runtimeMirror(classOf[Int].getClass.getClassLoader) + try println(m.symbolOf[C]) + catch { case ex: ScalaReflectionException => println(s"exception: ${ex.getMessage}") } + } + + test1 + test2 + test3 +} -- cgit v1.2.3
