Abstract Value Members

abstract def instance: Any

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

Reflects against an inner 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>.symbol.info.member(TypeName(<name of the class>)).asClass. For further information about member lookup refer to Symbol.info.

The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be a member (declared or inherited) of the instance underlying this mirror.

abstract def reflectField(field: Universe.TermSymbol): Universe.FieldMirror

Reflects against a field symbol and returns a mirror that can be used to get and, if appropriate, set the value of the field.

FieldMirrors are the only way to get at private[this] vals and vars and might be useful to inspect the data of underlying Java fields. For all other uses, it's better to go through the fields accessor.

In particular, there should be no need to ever access a field mirror when reflecting on just the public members of a class or trait. Note also that only accessor MethodMirrors, but not FieldMirrors will accurately reflect overriding behavior.

To get a field symbol by the name of the field you would like to reflect, use <this mirror>.symbol.info.member(TermName(<name of the field>)).asTerm.accessed. For further information about member lookup refer to Symbol.info.

The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be a member (declared or inherited) of the class of the instance underlying this mirror.

The input symbol can represent either a field itself or one of the corresponding accessors (in all cases the resulting mirror will refer to the field symbol).

If a field symbol doesn't correspond to a reflectable entity of the underlying platform, a ScalaReflectionException exception will be thrown. This might happen, for example, for primary constructor parameters. Typically they produce class fields, however, private parameters that aren't used outside the constructor remain plain parameters of a constructor method of the class.

abstract def reflectMethod(method: Universe.MethodSymbol): Universe.MethodMirror

Reflects against a method symbol and returns a mirror that can be used to invoke the method provided.

To get a method symbol by the name of the method you would like to reflect, use <this mirror>.symbol.info.member(TermName(<name of the method>)).asMethod. For further information about member lookup refer to Symbol.info.

The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be a member (declared or inherited) of the instance underlying this mirror.

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

Reflects against an inner 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 the object you would like to reflect, use <this mirror>.symbol.info.member(TermName(<name of the object>)).asModule. For further information about member lookup refer to Symbol.info.

The input symbol can be either private or non-private (Scala reflection transparently deals with visibility). It must be a member (declared or inherited) of the instance underlying this mirror.
