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

the type of the universe this mirror belongs to.

Abstract Value Members

  1. abstract def EmptyPackage: U.ModuleSymbol

    The module symbol of the default (unnamed) package

  2. abstract def EmptyPackageClass: U.ClassSymbol

    The module class symbol of the default (unnamed) package

  3. abstract def RootClass: U.ClassSymbol

    The class symbol of the _root_ package

  4. abstract def RootPackage: U.ModuleSymbol

    The module symbol of the _root_ package

  5. 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.

  6. 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.

  7. abstract def staticPackage(fullName: String): U.ModuleSymbol

    The symbol corresponding to a package with the given fully qualified name fullName.

  8. abstract def symbolOf[T](implicit arg0: U.WeakTypeTag[T]): U.TypeSymbol

    Type symbol of x as derived from a type tag.

  9. abstract val universe: U

    The universe this mirror belongs to.
