SolverModel

[python api] All information about the SolverModel Python object.

Description


This object is used to represent a model for an SMT solver.

Python API - Methods of the SolverModel class


  • integer getId(void)
    Returns the id of the model. This id is the same as the variable id.
  • integer getValue(void)
    Returns the value of the model.
  • SymbolicVariable getVariable(void)
    Returns the symbolic variable.
