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
Cmight refer to something else *inside* the class (i.e. as parameter type ofcopy) 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) isB.this.C- not the same.This is fixed with a hack currently.
Unapplies.caseClassCopyMeth, which creates the copy method, uses emptyTypeTree()nodes for parameter types.In
Namers.enterDefDef, the copy method gets a special type completer (enterCopyMethod). Before computing the body type ofcopy, 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.
