Trait scala.reflect.api.FlagSets.FlagValues

Flag used to distinguish platform-specific implementation details. Trees and symbols which are currently marked ARTIFACT by scalac: * $outer fields and accessors * super accessors * protected accessors * lazy local accessors * bridge methods * default argument getters * evaluation-order preserving locals for right-associative and out-of-order named arguments * catch-expression storing vals * anything else which feels a setFlag(ARTIFACT)

Flag indicating that tree represents a parameter of the primary constructor of some case class or a synthetic member underlying thereof. E.g. here's how 'case class C(val x: Int)' is represented:

trees at end of parser// Scala source: tmpnHkJ3y case class C extends scala.Product with scala.Serializable { <caseaccessor> <paramaccessor> val x: Int = _; def <init>(x: Int) = { super.<init>(); () } } ClassDef( Modifiers(CASE), TypeName("C"), List(), Template( List(Select(Ident(scala), TypeName("Product")), Select(Ident(scala), TypeName("Serializable"))), noSelfType, List( ValDef(Modifiers(CASEACCESSOR | PARAMACCESSOR), TermName("x"), Ident(TypeName("Int")), EmptyTree), DefDef( Modifiers(), nme.CONSTRUCTOR, List(), List(List(ValDef(Modifiers(PARAM | PARAMACCESSOR), TermName("x"), Ident(TypeName("Int")), EmptyTree))), TypeTree(), Block(List(pendingSuperCall), Literal(Constant(())))))))))

Flag indicating that a tree is an interface (i.e. a trait which defines only abstract methods)

Flag indicating that tree represents a member local to current class, i.e. private[this] or protected[this]. This requires having either PRIVATE or PROTECTED set as well.

Flag indicating that tree represents a class or parameter. Both type and value parameters carry the flag.

Flag indicating that tree represents a parameter of the primary constructor of some class or a synthetic member underlying thereof. E.g. here's how 'class C(val x: Int)' is represented:

trees at end of parser// Scala source: tmposDU52 class C extends scala.AnyRef { <paramaccessor> val x: Int = _; def <init>(x: Int) = { super.<init>(); () } } ClassDef( Modifiers(), TypeName("C"), List(), Template( List(Select(Ident(scala), TypeName("AnyRef"))), noSelfType, List( ValDef(Modifiers(PARAMACCESSOR), TermName("x"), Ident(TypeName("Int")), EmptyTree), DefDef( Modifiers(), nme.CONSTRUCTOR, List(), List(List(ValDef(Modifiers(PARAM | PARAMACCESSOR), TermName("x"), Ident(TypeName("Int")), EmptyTree))), TypeTree(), Block(List(pendingSuperCall), Literal(Constant(())))))))))

Flag that indicates methods that are supposed to be stable (e.g. synthetic getters of valdefs).

Flag used to distinguish programmatically generated definitions from user-written ones.

Flag indicating that tree represents an enum.

It can only appear at

the enum's classenum constants
