    Extend the argument list givenArgs with default arguments.

    Extend the argument list givenArgs with default arguments. Defaults are added as named arguments calling the corresponding default getter.

    Example: given def foo(x: Int = 2, y: String = "def") foo(y = "lt") the argument list (y = "lt") is transformed to (y = "lt", x = foo$default$1())

  5. def allArgsArePositional(a: Array[Int]): Boolean

    Returns the parameter symbols of an invocation expression that are not defined by the list of arguments.

    Returns the parameter symbols of an invocation expression that are not defined by the list of arguments.

    args

    The list of arguments

    params

    The list of parameter symbols of the invoked method

    argName

    A function that extracts the name of an argument expression, if it is a named argument.

  22. def removeNames(typer: Analyzer.Typer)(args: List[Global.Tree], params: List[Global.Symbol]): (List[Global.Tree], Array[Int])

    Removes name assignments from args.

    Removes name assignments from args. Additionally, returns an array mapping argument indices from call-site-order to definition-site-order.

    Verifies that names are not specified twice, and positional args don't appear after named ones.

  23. def reorderArgs[T](args: List[T], pos: (Int) ⇒ Int)(implicit arg0: ClassTag[T]): List[T]

    pos

    maps indices from old to new

  26. def transformNamedApplication(typer: Analyzer.Typer, mode: Mode, pt: Global.Type)(tree: Global.Tree, argPos: (Int) ⇒ Int): Global.Tree

    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

    returns

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