Inherited from Backend (via BackendZ3):

Method apply_annotation This should apply the annotation on the backend object, and return a new backend object.
Method batch_eval Evaluate one or multiple expressions.
Method cardinality This should return the maximum number of values that an expression can take on. This should be a strict *over* approximation.
Method check_satisfiability This function does a constraint check and returns the solvers state
Method convert Resolves a claripy.ast.Base into something usable by the backend.
Method convert_list Undocumented
Method default_op Undocumented
Method eval This function returns up to `n` possible solutions for expression `expr`.
Method handles Checks whether this backend can handle the expression.
Method has_false Should return False if `e` can possibly be False.
Method has_true Should return True if `e` can possible be True.
Method identical This should return whether `a` is identical to `b`. Of course, this isn't always clear. True should mean that it is definitely identical. False eans that, conservatively, it might not be.
Method is_false Should return True if e can be easily found to be False.
Method is_true Should return True if `e` can be easily found to be True.
Method max Return the maximum value of expr.

Method multivalued Undocumented
Method name This should return the name of an expression.
Method satisfiable This function does a constraint check and checks if the solver is in a sat state.
Method singlevalued Undocumented
Method solution Return True if `v` is a solution of `expr` with the extra constraints, False otherwise.
Method unsat_core This function returns the unsat core from the backend solver.
