final case class FlagSet(bits: Long) extends AnyVal with Product with Serializable

A FlagSet represents a set of flags. Flags are encoded as follows: The first two bits indicate whether a flagset applies to terms, to types, or to both. Bits 2..63 are available for properties and can be doubly used for terms and types. Combining two FlagSets with | will give a FlagSet that has the intersection of the applicability to terms/types of the two flag sets. It is checked that the intersection is not empty.

  12. def is(flags: FlagConjunction, butNot: FlagSet): Boolean

    Does this flag set have all of the flags in given flag conjunction? and at the same time contain none of the flags in the butNot set? Pre: The intersection of the typeflags of both sets must be non-empty.

  13. def is(flags: FlagConjunction): Boolean

    Does this flag set have all of the flags in given flag conjunction? Pre: The intersection of the typeflags of both sets must be non-empty.

  14. def is(flags: FlagSet, butNot: FlagSet): Boolean
