abstract class Mirror[U <: Universe with Singleton] extends AnyRef
EXPERIMENTAL
The base class for all mirrors.
See scala.reflect.api.Mirrors or Reflection Guide
for a complete overview of Mirrors.
- U

Mirror
- abstract def EmptyPackage: U.ModuleSymbol
The module symbol of the default (unnamed) package
- abstract def EmptyPackageClass: U.ClassSymbol
The module class symbol of the default (unnamed) package
- abstract def RootClass: U.ClassSymbol
The class symbol of the
_root_package - abstract def RootPackage: U.ModuleSymbol
The module symbol of the
_root_package - abstract def staticClass(fullName: String): U.ClassSymbol
The symbol corresponding to the globally accessible class with the given fully qualified name
fullName.The symbol corresponding to the globally accessible class with the given fully qualified name
fullName.If the name points to a type alias, it's recursively dealiased and its target is returned. If you need a symbol that corresponds to the type alias itself, load it directly from the package class:
scala> cm.staticClass("scala.List") res0: scala.reflect.runtime.universe.ClassSymbol = class List
scala> res0.fullName res1: String = scala.collection.immutable.List
scala> cm.staticPackage("scala") res2: scala.reflect.runtime.universe.ModuleSymbol = package scala
scala> res2.moduleClass.info member TypeName("List") res3: scala.reflect.runtime.universe.Symbol = type List
scala> res3.fullName res4: String = scala.List
To be consistent with Scala name resolution rules, in case of ambiguity between a package and an object, the object is never been considered.
For example for the following code:
package foo { class B }
object foo { class A class B }
staticClass("foo.B") will resolve to the symbol corresponding to the class B declared in the package foo, and staticClass("foo.A") will throw a ScalaReflectionException.
In the example above, to load a symbol that corresponds to the class B declared in the object foo, use staticModule("foo") to load the module symbol and then navigate info.members of its moduleClass.
- abstract def staticModule(fullName: String): U.ModuleSymbol
The symbol corresponding to the globally accessible object with the given fully qualified name
fullName.The symbol corresponding to the globally accessible object with the given fully qualified name
fullName.To be consistent with Scala name resolution rules, in case of ambiguity between a package and an object, the object is never been considered.
For example for the following code:
package foo { object B }
object foo { object A object B }
staticModule("foo.B") will resolve to the symbol corresponding to the object B declared in the package foo, and staticModule("foo.A") will throw a ScalaReflectionException
In the example above, to load a symbol that corresponds to the object B declared in the object foo, use staticModule("foo") to load the module symbol and then navigate info.members of its moduleClass.
- abstract def staticPackage(fullName: String): U.ModuleSymbol
The symbol corresponding to a package with the given fully qualified name
fullName. - abstract val universe: U
The universe this mirror belongs to.
