FastTypeTag

A "tag" denoting information about a runtime type. This tag is meant to be extermely efficient for simple runtime checks, avoiding a full reflection overhead, while also *allowing* full runtime checks.

Notes:

1. Currently the equals method does "stringy" comparison of types. For a full equality comparison, you'll need to fully reify the Type (tpe). 2. Calling mirror or tpe may cause runtime reflection to be used.

Abstract Value Members

abstract def key: String

A stringified key that can be used to denote this type.
A stringified key that can be used to denote this type. This key should be unique for types within scala, although the key will *not* determine uniqueness between types loaded on different classloaders.
returns
A stringy type key.
abstract def mirror: reflect.api.JavaUniverse.Mirror

returns
The mirror known to be in use when this FastTypeTag was created.
It is not guaranteed to be the correct mirror to reify the type against.
abstract def tpe: reflect.api.JavaUniverse.Type

returns
The full Type of T. This method may need to use runtime reflection to reconstruct the full type.
