bool ProgramState::scanReachableSymbols | ( | SVal | val, |
SymbolVisitor & | visitor | ||
) | const |
Visits the symbols reachable from the given SVal using the provided SymbolVisitor.
This is a convenience API. Consider using ScanReachableSymbols class directly when making multiple scans on the same state with the same visitor to avoid repeated initialization cost.
