Enum SMTSolverResult.ThreeValuedTruth

java.lang.Object

java.lang.Enum<SMTSolverResult.ThreeValuedTruth>

de.uka.ilkd.key.smt.SMTSolverResult.ThreeValuedTruth

All Implemented Interfaces:

Serializable, Comparable<SMTSolverResult.ThreeValuedTruth>

Enclosing class:

SMTSolverResult

public static enum SMTSolverResult.ThreeValuedTruth
extends Enum<SMTSolverResult.ThreeValuedTruth>

In the context of proving nodes/sequents these values mean the following: TRUE iff negation of the sequent is unsatisfiable, FALSIFIABLE iff negation of the sequent is satisfiable (i.e. it has a counterexample), UNKNOWN otherwise (I'm not sure if this holds if an error occurs) Note: Currently (1.12.'09) the SMT Solvers do not check if a node is FALSE.

Method Detail

values

public static SMTSolverResult.ThreeValuedTruth[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SMTSolverResult.ThreeValuedTruth c : SMTSolverResult.ThreeValuedTruth.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SMTSolverResult.ThreeValuedTruth valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
