trait JavaMirror extends api.Mirror[JavaUniverse.this.type] with RuntimeMirror

A refinement of scala.reflect.api.Mirror for runtime reflection using JVM classloaders.

With this upgrade, mirrors become capable of converting Scala reflection artifacts (symbols and types) into Java reflection artifacts (classes) and vice versa. Consequently, refined mirrors become capable of performing reflective invocations (getting/setting field values, calling methods, etc).

For more information about Mirrorss, see scala.reflect.api.Mirrors or the Reflection Guide: Mirrors

  8. abstract def reflect[T](obj: T)(implicit arg0: ClassTag[T]): JavaUniverse.InstanceMirror

    A reflective mirror for the given object.

    A reflective mirror for the given object.

    Such a mirror can be used to further reflect against the members of the object to get/set fields, invoke methods and inspect inner classes and objects.

  9. abstract def reflectClass(cls: JavaUniverse.ClassSymbol): JavaUniverse.ClassMirror

    Reflects against a static class symbol and returns a mirror that can be used to create instances of the class, inspect its companion object or perform further reflections.

    Reflects against a static class symbol and returns a mirror that can be used to create instances of the class, inspect its companion object or perform further reflections.

    To get a class symbol by the name of the class you would like to reflect, use <this mirror>.classSymbol(<runtime class loaded by its name>).

    The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be static, i.e. either top-level or nested within one or several static objects.

  10. abstract def reflectModule(mod: JavaUniverse.ModuleSymbol): JavaUniverse.ModuleMirror

    Reflects against a static module symbol and returns a mirror that can be used to get the instance of the object or inspect its companion class.

    Reflects against a static module symbol and returns a mirror that can be used to get the instance of the object or inspect its companion class.

    To get a module symbol by the name of its companion class you would like to reflect, use <this mirror>.classSymbol(<runtime class loaded by its name>).companion.get.

    The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be static, i.e. either top-level or nested within one or several static objects.

  11. abstract def runtimeClass(cls: JavaUniverse.ClassSymbol): RuntimeClass

    Maps a Scala class symbol to the corresponding Java class object

    Maps a Scala class symbol to the corresponding Java class object

    Definition Classes
    RuntimeMirror
    Exceptions thrown

    ClassNotFoundException if there is no Java class corresponding to the given Scala class symbol. Note: If the Scala symbol is ArrayClass, a ClassNotFound exception is thrown because there is no unique Java class corresponding to a Scala generic array

  12. abstract def runtimeClass(tpe: JavaUniverse.Type): RuntimeClass

    Maps a Scala type to the corresponding Java class object

    Maps a Scala type to the corresponding Java class object

    Definition Classes
    RuntimeMirror
  13. abstract def staticClass(fullName: String): JavaUniverse.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.
