Value

dotty.tools.dotc.transform.init.Semantic.Value
sealed abstract class Value

Abstract values

Value = Hot | Cold | Warm | ThisRef | Fun | RefSet

           Cold
  ┌──────►  ▲  ◄────┐  ◄────┐
  │         │       │       │
  │         │       │       │
  |         │       │       │

ThisRef Warm Fun RefSet │ ▲ ▲ ▲ │ │ │ │ | │ │ │ ▲ │ │ │ │ │ │ │ └─────────┴───────┴───────┘ Hot

The diagram above does not reflect relationship between RefSet and other values. RefSet represents a set of values which could be ThisRef, Warm or Fun. The following ordering applies for RefSet:

   R_a ⊑ R_b if R_a ⊆ R_b

   V ⊑ R if V ∈ R
