    The goal of this method is to find a class that is accessible (in bytecode) and can be used to select member. - For constructors, it returns the member.owner. We can assume the class is accessible: if it wasn't, the typer would have rejected the program, as the class is referenced in source. - For Scala-defined members it also returns member.owner, all Scala-defined classes are public in bytecode. - For Java-defined members we prefer a direct parent over of the owner, even if the owner is accessible. This way the owner doesn't need to be added as a direct parent, see scala-dev#143.

    Generates copy methods for case classes.

    Generates copy methods for case classes. Copy only has defaults on the first parameter list, as of scala/bug#5009.

    The parameter types of the copy method need to be exactly the same as the parameter types of the primary constructor. Just copying the TypeTree is not enough: a type C might refer to something else *inside* the class (i.e. as parameter type of copy) than *outside* the class (i.e. in the class parameter list).

    One such example is t0054.scala: class A { case class B(x: C) extends A { def copy(x: C = x) = ... } class C {} } (1) (2)

    The reference (1) to C is A.this.C. The reference (2) is B.this.C - not the same.

    This is fixed with a hack currently. Unapplies.caseClassCopyMeth, which creates the copy method, uses empty TypeTree() nodes for parameter types.

    In Namers.enterDefDef, the copy method gets a special type completer (enterCopyMethod). Before computing the body type of copy, the class parameter types are assigned the copy method parameters.

    This attachment class stores the copy method parameter ValDefs as an attachment in the ClassDef of the case class.

    Does this symbol compile to the underlying platform's notion of an interface, without requiring compiler magic before it can be instantiated?

    More specifically, we're interested in whether LambdaMetaFactory can instantiate this type, assuming it has a single abstract method. In other words, if we were to mix this trait into a class, it should not result in any compiler-generated members having to be implemented in ("mixed in to") this class (except for the SAM).

    Thus, the type must erase to a java interface, either by virtue of being defined as one, or by being a trait that:

    • is static (explicitouter or lambdalift may add disqualifying members)
    • extends only other traits that compile to pure interfaces (except for Any)
    • has no val/var members

    For some macros this might be ok (thanks to TreeTypeSubstituter that replaces the occurrences of undetparams with their inferred values), but in general case this won't work. E.g. for reification simple substitution is not enough - we actually need to re-reify inferred types.

    Luckily, there exists a very simple way to fix the problem: delay macro expansion until everything is inferred. Here are the exact rules. Macro application gets delayed if any of its subtrees contain: 1) type vars (tpe.isInstanceOf[TypeVar]) // [Eugene] this check is disabled right now, because TypeVars seem to be created from undetparams anyways 2) undetparams (sym.isTypeParameter && !sym.isSkolem)

     Transform a function application into a Block, and assigns typer.context .namedApplyBlockInfo to the new block as side-effect.

     Transform a function application into a Block, and assigns typer.context .namedApplyBlockInfo to the new block as side-effect. If tree has the form Apply(fun, args) first the function "fun" (which might be an application itself!) is transformed into a block of the form { val qual$1 = qualifier_of_fun val x$1 = arg_1_of_fun ... val x$n = arg_n_of_fun qual$1.fun[targs](x$1, ...)...(..., x$n) } then for each argument in args, a value is created and entered into the block. finally the application expression of the block is updated. { val qual$1 = .. ... val x$n = ... > val qual$n+1 = arg(1) > ... > val qual$n+m = arg(m) > qual$1.fun[targs](x$1, ...)...(..., x$n)(x$n+1, ..., x$n+m) }

     typer

     the typer calling this method; this method calls typer.doTypedApply

     mode

     the mode to use for calling typer.doTypedApply

     pt

     the expected type for calling typer.doTypedApply

     tree

     the function application tree

     argPos

     a function mapping arguments from their current position to the position specified by the method type. example: def foo(a: Int, b: String) foo(b = "1", a = 2) calls transformNamedApplication(Apply(foo, List("1", 2), { 0 => 1, 1 => 0 })

     returns

     the transformed application (a Block) together with the NamedApplyInfo. if isNamedApplyBlock(tree), returns the existing context.namedApplyBlockInfo

232.  def transformTypeTagEvidenceParams(macroImplRef: Global.Tree, transform: (Global.Symbol, Global.Symbol) => Global.Symbol): List[List[Global.Symbol]]

     Transforms parameters lists of a macro impl.

     Transforms parameters lists of a macro impl. The transform function is invoked only for WeakTypeTag evidence parameters.

     The transformer takes two arguments: a value parameter from the parameter list and a type parameter that is witnesses by the value parameter.

     If the transformer returns a NoSymbol, the value parameter is not included from the result. If the transformer returns something else, this something else is included in the result instead of the value parameter.

     Despite of being highly esoteric, this function significantly simplifies signature analysis. For example, it can be used to strip macroImpl.paramss from the evidences (necessary when checking def <-> impl correspondence) or to streamline creation of the list of macro arguments.
