  8. def caseClassCopyMeth(cdef: Global.ClassDef): Option[Global.DefDef]

    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.

    Deprecated

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