addSelfFlag()

static void addSelfFlag ( ProgramStateRef  state, SVal  val, SelfFlagEnum  flag, CheckerContext &  C  )

getSelfFlags() [1/2]

static SelfFlagEnum getSelfFlags ( SVal  val, CheckerContext &  C  )

getSelfFlags() [2/2]

static SelfFlagEnum getSelfFlags ( SVal  val, ProgramStateRef  state  )

static

A call receiving a reference to 'self' invalidates the object that 'self' contains.

This keeps the "self flags" assigned to the 'self' object before the call so we can assign them to the new object that 'self' points to after the call.
