| virtual void | set_to (const exprt &, bool value)=0 |
For a Boolean expression expr, add the constraint 'expr' if value is true, otherwise add 'not expr'. | |
| void | set_to_true (const exprt &) |
For a Boolean expression expr, add the constraint 'expr'. | |
| void | set_to_false (const exprt &) |
For a Boolean expression expr, add the constraint 'not expr'. | |
| virtual exprt | handle (const exprt &)=0 |
| Generate a handle, which is an expression that has the same value as the argument in any model that is generated; this offers an efficient way to refer to the expression in subsequent calls to get or set_to. | |
| resultt | operator() () |
| Run the decision procedure to solve the problem This corresponds to SMT-LIB's check-sat. | |
| resultt | operator() (const exprt &assumption) |
| Run the decision procedure to solve the problem under the given assumption. | |
| virtual exprt | get (const exprt &) const =0 |
Return expr with variables replaced by values from satisfying assignment if available. | |

Print satisfying assignment to out. | |

Member Function Documentation
◆ pop()
Pop whatever is on top of the stack.
Popping from the empty stack results in an invariant violation.
Implemented in prop_conv_solvert, smt2_convt, and smt2_incremental_decision_proceduret.
◆ push() [1/2]
Push a new context on the stack This context becomes a child context nested in the current context.
Implemented in prop_conv_solvert, smt2_convt, and smt2_incremental_decision_proceduret.
◆ push() [2/2]

pure virtual |
Pushes a new context on the stack that consists of the given (possibly empty vector of) assumptions.
This context becomes a child context nested in the current context. An assumption is usually obtained by calling decision_proceduret::handle. Thus it can be a Boolean expression or something more solver-specific such as literal_exprt. An empty vector of assumptions counts as an element on the stack (and therefore needs to be popped), but has no effect beyond that.
Implemented in smt2_convt, prop_conv_solvert, and smt2_incremental_decision_proceduret.
