A class symbol for the specified runtime class.
The class symbol for the runtime class in the current class loader.
java.lang.ClassNotFoundException
if no class with that name exists
scala.reflect.ScalaReflectionException
if no corresponding symbol exists to do: throws anything else?
A module symbol for the specified runtime class.
The module symbol for the runtime class in the current class loader.

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.
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.

Maps a Scala class symbol to the corresponding Java class object
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
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.
