Rose::BinaryAnalysis::ModelChecker::LongestPathFirst Class Reference


Prioritize longer paths.

Paths that are longer (more steps) get higher priority. When used with the work queue, this results in a depth-first search of the virtual execution tree.

Priority predicate.

Given two paths, return true if path better should be explored before path worse, and false otherwise. This must be a strict weak ordering.

Note that the ordering predicate for C++ heaps is opposite the predicate for sorting containers with operator<. In other words, the item with the highest priority (not the lowest) is the one that will be taken next from the heap.

Thread safety: This method is thread safe. The base implementation is thread safe and all subclass implementations must also be thread safe.
