trait Names extends AnyRef

EXPERIMENTAL

This trait defines Names in Scala Reflection, and operations on them.

Names are simple wrappers for strings. Name has two subtypes TermName and TypeName which distinguish names of terms (like objects or members) and types. A term and a type of the same name can co-exist in an object.

To search for the map method (which is a term) declared in the List class, one can do:

scala> typeOf[List[_]].member(TermName("map"))
res0: reflect.runtime.universe.Symbol = method map

To search for a type member, one can follow the same procedure, using TypeName instead.

For more information about creating and using Names, see the Reflection Guide: Annotations, Names, Scopes, and More

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.

  2. def stringToTermName(s: String): TermName

    A former implicit conversion from String to TermName.

    A former implicit conversion from String to TermName.

    This used to be an implicit conversion, enabling an alternative notation "map": TermName as opposed to TermName("map"). It is only kept for binary compatibility reasons, and should not be used anymore.

Names

API

The methods available for each reflection entity, without the implementation. Since the reflection entities are later overridden by runtime reflection and macros, their API counterparts guarantee a minimum set of methods that are implemented.

Extractors

Extractors provide the machinery necessary to allow pattern matching and construction of reflection entities that is similar to case classes, although the entities are only abstract types that are later overridden.
