Trait scala.reflect.api.TypeTags.WeakTypeTag

Companion object WeakTypeTag

trait WeakTypeTag[T] extends Equals with Serializable

If an implicit value of type WeakTypeTag[T] is required, the compiler will create one, and the reflective representation of T can be accessed via the tpe field. Components of T can be references to type parameters or abstract types. Note that WeakTypeTag makes an effort to be as concrete as possible, i.e. if TypeTags are available for the referenced type arguments or abstract types, they are used to embed the concrete types into the WeakTypeTag. Otherwise the WeakTypeTag will contain a reference to an abstract type. This behavior can be useful, when one expects T to be perhaps be partially abstract, but requires special care to handle this case. However, if T is expected to be fully known, use scala.reflect.api.TypeTags#TypeTag instead, which statically guarantees this property.

Abstract Value Members

abstract def in[U <: Universe with Singleton](otherMirror: Mirror[U]): in.U.WeakTypeTag[T]

Migrates the expression into another mirror, jumping into a different universe if necessary.

Migration means that all symbolic references to classes/objects/packages in the expression will be re-resolved within the new mirror (typically using that mirror's classloader).

abstract val mirror: Universe.Mirror

abstract def tpe: Universe.Type
