.Collects all the symbols defined by subtrees of
tree
that are owned byprev
, and then changes their owner to point tonext
.This is an essential tool to battle owner chain corruption when moving trees from one lexical context to another. Whenever you take an attributed tree that has been typechecked under the Context owned by some symbol (let's call it
x
) and splice it elsewhere, into the Context owned by another symbol (let's call ity
), it is imperative that you either calluntypecheck
or dochangeOwner(tree, x, y)
.Since at the moment
untypecheck
has fundamental problem that can sometimes lead to tree corruption,changeOwner
becomes an indispensable tool in building 100% robust macros. Future versions of the reflection API might obviate the need in taking care of these low-level details, but at the moment this is what we've got.- Definition Classes

- abstract def deSkolemize(symbol: Universe.Symbol): Universe.Symbol
If this symbol is a skolem, its corresponding type parameter, otherwise the symbol itself.
If this symbol is a skolem, its corresponding type parameter, otherwise the symbol itself.
To quote Martin Odersky, skolems are synthetic type "constants" that are copies of existentially bound or universally bound type variables. E.g. if one is inside the right-hand side of a method:
def foo[T](x: T) = ... foo[List[T]]....
the skolem named
T
refers to the unknown type instance ofT
whenfoo
is called. It needs to be different from the type parameter because in a recursive call as in thefoo[List[T]]
above the type parameter gets substituted withList[T]
, but the type skolem stays what it is.The other form of skolem is an existential skolem. Say one has a function
def bar(xs: List[T] forSome { type T }) = xs.head
then each occurrence of
xs
on the right will have typeList[T']
whereT'
is a fresh copy ofT

Like

will snap back.Like
setType
, but if this is a previously empty TypeTree that fact is remembered so thatuntypecheck
will snap back.\@PP: Attempting to elaborate on the above, I find: If defineType is called on a TypeTree whose type field is null or NoType, this is recorded as "wasEmpty = true". That value is used in ResetAttrsTraverser, which nulls out the type field of TypeTrees for which wasEmpty is true, leaving the others alone.
untypecheck
(orresetAttrs
in compiler parlance) is used in situations where some speculative typing of a tree takes place, fails, and the tree needs to be returned to its former state to try again. So according to me: usingdefineType
instead ofsetType
is how you communicate that the type being set does not depend on any previous state, and therefore should be abandoned if the current line of type inquiry doesn't work out.- Definition Classes

. Extrapolating means that type variables intparams
occurring in covariant positions are replaced by upper bounds, (minus any SingletonClass markers), type variables intparams
occurring in contravariant positions are replaced by upper bounds, provided the resulting type is legal with regard to stability, and does not contain any type variable intparams
.The abstraction drops all type parameters that are not directly or indirectly referenced by type
tpe1
. If there are no remaining type parameters, simply returns result typetpe

Convert a scala.reflect.api.TypeTags#TypeTag to a scala.reflect.Manifest.
Convert a scala.reflect.api.TypeTags#TypeTag to a scala.reflect.Manifest.
Compiler usually generates these conversions automatically, when a type tag for a type
T
is in scope, and an implicit of typeManifest[T]
is requested, but this method can also be called manually. For example:typeTagToManifest(scala.reflect.runtime.currentMirror, implicitly[TypeTag[String]])
