formalTypes(formals: List[Global.Type], numArgs: Int, removeByName: Boolean = true, removeRepeated: Boolean = true): List[Global.Type]
The formal parameter types corresponding to
formals.The formal parameter types corresponding to
formals. Ifformalshas a repeated last parameter, a list of (numArgs - numFormals + 1) copies of its type is appended to the other formals. By-name types are replaced with their underlying type.- removeByName
allows keeping ByName parameters. Used in NamesDefaults.
- removeRepeated
allows keeping repeated parameter (if there's one argument). Used in NamesDefaults.

normalize(tp: Global.Type): Global.Type
Automatically perform the following conversions on expression types: A method type becomes the corresponding function type.
Automatically perform the following conversions on expression types: A method type becomes the corresponding function type. A nullary method type becomes its result type. Implicit parameters are skipped. This method seems to be performance critical.

- Deprecated
(Since version 2.12.16) Use
formatString.format(value)instead ofvalue.formatted(formatString), or use thef""string interpolator. In Java 15 and later,formattedresolves to the new method in String which has reversed parameters.
