NON_ZERO

public static final DivisionByZeroCheck.ZeroConstraint NON_ZERO

Method Detail

values

public static DivisionByZeroCheck.ZeroConstraint[] 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 (DivisionByZeroCheck.ZeroConstraint c : DivisionByZeroCheck.ZeroConstraint.values())
    System.out.println(c);

Returns:

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

valueOf

public static DivisionByZeroCheck.ZeroConstraint 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

hasPreciseValue

public boolean hasPreciseValue()

Specified by:

hasPreciseValue in interface Constraint

Returns:

true if value represented by this SV is precisely known.

valueAsString

public String valueAsString()

Specified by:

valueAsString in interface Constraint

Returns:

String representation of value encoded by constraint for purpose of flow message

isValidWith

public boolean isValidWith(@Nullable
                           Constraint constraint)

Specified by:

isValidWith in interface Constraint

copyOver

@Nullable
public Constraint copyOver(RelationalSymbolicValue.Kind kind)

Description copied from interface: Constraint

Return constraint which should be applied to the rhs of the relation, if this constraint is set on the lhs of the relation.

Specified by:

copyOver in interface Constraint

Parameters:

kind - kind of relation over which constraint is copied

Returns:

constraint to be set on rhs, null if no constraint should be set

inverse

public Constraint inverse()

Specified by:

inverse in interface Constraint
