abstract class RefChecks extends SubComponent with Transform

Post-attribution checking and transformation.

This phase performs the following checks.

  • All overrides conform to rules.
  • All type arguments conform to bounds.
  • All type variable uses conform to variance annotations.
  • No forward reference to a term symbol extends beyond a value definition.

It performs the following transformations.

  • Local modules are replaced by variables and classes
  • Calls to case factory methods are replaced by new's.
  • Eliminate branches in a conditional if the condition is a constant
