TypeCreators

  1. abstract def existentialAbstraction(tparams: List[Universe.Symbol], tpe0: Universe.Type): Universe.Type

    Permalink

    A creator for existential types.

    A creator for existential types. This generates:

    tpe1 where { tparams }

    where tpe1 is the result of extrapolating tpe with regard to tparams. Extrapolating means that type variables in tparams occurring in covariant positions are replaced by upper bounds, (minus any SingletonClass markers), type variables in tparams 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 in tparams.

    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 type tpe.

    Collects all the symbols defined by subtrees of tree that are owned by prev, and then changes their owner to point to next.

    Collects all the symbols defined by subtrees of tree that are owned by prev, and then changes their owner to point to next.

    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 it y), it is imperative that you either call untypecheck or do changeOwner(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.

  12. abstract def deSkolemize(symbol: Universe.Symbol): Universe.Symbol

    Permalink

    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 of T when foo is called. It needs to be different from the type parameter because in a recursive call as in the foo[List[T]] above the type parameter gets substituted with List[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 type List[T'] where T' is a fresh copy of T.

    Like setType, but if this is a previously empty TypeTree that fact is remembered so that untypecheck will snap back.

    Like setType, but if this is a previously empty TypeTree that fact is remembered so that untypecheck 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 (or resetAttrs 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: using defineType instead of setType 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.

    Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

    returns

    a hash value consistent with ==

    Cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

    Permalink

    Tests whether the argument (that) is a reference to the receiver object (this).

    Tests whether the argument (that) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    returns

    true if the argument is a reference to the receiver object; false otherwise.
