Module MakeImplCommon::Cached::FlowThrough::Final

The final flow-through calculation:

  • Calculated flow is either value-preserving (read = TReadStepTypesNone()) or summarized as a single read step with before and after types recorded in the ReadStepTypesOption parameter.
  • Types are checked using the compatibleTypes() relation.

Predicates

argumentValueFlowsThrough

Holds if arg flows to out through a call using only value-preserving steps and possibly a single read step, not taking call contexts into account.

getterStep

Holds if arg flows to out through a call using only value-preserving steps and a single read step, not taking call contexts into account, thus representing a getter-step.

parameterValueFlow

Holds if p can flow to node in the same callable using only value-preserving steps and possibly a single read step, not taking call contexts into account.
