Definition: namespace.h:92
Uses goto-symex to generate a symex_target_equationt for each path.
virtual bool is_ready_to_decide(const symex_bmct &symex, const path_storaget::patht &path)
Returns whether the given path produced by symex is ready to be checked.
virtual void final_update_properties(propertiest &properties, std::unordered_set< irep_idt > &updated_properties)
Updates the properties after having finished exploration and adds their property IDs to updated_prope...
virtual void initialize_worklist()
Adds the initial goto-symex state as a path to the worklist.

virtual void update_properties(propertiest &properties, std::unordered_set< irep_idt > &updated_properties, const symex_target_equationt &equation)
Updates the properties from the equation and adds their property IDs to updated_properties.

virtual bool resume_path(path_storaget::patht &path)
Continues exploring the given path using goto-symex.
virtual bool has_finished_exploration(const propertiest &)
Returns whether we should stop exploring paths.
