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

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.

abstract def reflectClass(cls: Universe.ClassSymbol): Universe.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.

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.

abstract def reflectModule(mod: Universe.ModuleSymbol): Universe.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.

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.

abstract def staticClass(fullName: String): Universe.ClassSymbol

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): Universe.ModuleSymbol

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.
