공개 메소드들

메소드	설명
Add ( ) : void	Alias for Assert.
AddCover ( int level, FuncDecl predicate, Expr property ) : void	Add `property` about the `predicate`. The property is added at `level`.
AddFact ( FuncDecl pred ) : void	Add table fact to the fixedpoint solver.
AddRule ( BoolExpr rule, Symbol name = null ) : void	Add rule into the fixedpoint solver.
Assert ( ) : void	Assert a constraint (or multiple) into the fixedpoint solver.
GetAnswer ( ) : Expr	Retrieve satisfying instance or instances of solver, or definitions for the recursive predicates that show unsatisfiability.
GetCoverDelta ( int level, FuncDecl predicate ) : Expr	Retrieve the cover of a predicate.
GetNumLevels ( FuncDecl predicate ) : uint	Retrieve the number of levels explored for a given predicate.
GetReasonUnknown ( ) : string	Retrieve explanation why fixedpoint engine returned status Unknown.
ParseFile ( string file ) : Microsoft.Z3.BoolExpr[]	Parse an SMT-LIB2 file with fixedpoint rules. Add the rules to the current fixedpoint context. Return the set of queries in the file.
ParseString ( string s ) : Microsoft.Z3.BoolExpr[]	Similar to ParseFile. Instead it takes as argument a string.
Pop ( ) : void	Backtrack one backtracking point. Note that an exception is thrown if Pop is called without a corresponding `Push`
Push ( ) : void	Creates a backtracking point.
Query ( BoolExpr query ) : Status	Query the fixedpoint solver. A query is a conjunction of constraints. The constraints may include the recursively defined relations. The query is satisfiable if there is an instance of the query variables and a derivation for it. The query is unsatisfiable if there are no derivations satisfying the query variables.
Query ( FuncDecl relations ) : Status	Query the fixedpoint solver. A query is an array of relations. The query is satisfiable if there is an instance of some relation that is non-empty. The query is unsatisfiable if there are no derivations satisfying any of the relations.
RegisterRelation ( FuncDecl f ) : void	Register predicate as recursive relation.
SetPredicateRepresentation ( FuncDecl f, Symbol kinds ) : void	Instrument the Datalog engine on which table representation to use for recursive predicate.
ToString ( ) : string	Retrieve internal string representation of fixedpoint object.
ToString ( BoolExpr queries ) : string	Convert benchmark given as set of axioms, rules and queries to a string.
UpdateRule ( BoolExpr rule, Symbol name ) : void	Update named rule into in the fixedpoint solver.
