Detailed Description

Member Function Documentation
◆ clear()
|
overridevirtual |
Clear all saved paths.
This is typically used because we want to terminate symbolic execution early. It doesn't matter too much in terms of memory usage since CBMC typically exits soon after we do that, however it's nice to have tests that check that the worklist is always empty when symex finishes.
