Rose::BinaryAnalysis::SmtSolver::Transaction Class Reference

Description

RAII guard for solver stack.

This object implements a rudimentary form of SMT transactions. The constructor starts a new transaction by pushing a new level onto the specified solver (if the solver is non-null). The destructor pops transactions until it gets back to the same number of levels as originally. It is undefined behavior if the solver has fewer transactions than originally when the destructor is called. If commit has been called on this object then the destructor does nothing.

This guard object makes no attempt to ensure that after popping levels we end up at the same level we started at. In other words, although the number of levels is back to where we started, it might have been possible that between the constructor and destructor we popped past this transaction and then pushed new transactions to replace it with a different transaction.

Constructor & Destructor Documentation

Rose::BinaryAnalysis::SmtSolver::Transaction::Transaction ( const SmtSolver::Ptr &  solver )

inlineexplicit

Constructor pushes level if solver is non-null.

It is safe to call this with a null solver.
