public interface Constraint

Method Summary

Modifier and Type	Method and Description
default Constraint	copyOver(RelationalSymbolicValue.Kind kind) Return constraint which should be applied to the rhs of the relation, if this constraint is set on the lhs of the relation.
default boolean	hasPreciseValue()
default Constraint	inverse()
default boolean	isValidWith(Constraint constraint)
default String	valueAsString()

Method Detail

valueAsString

default String valueAsString()

Returns:

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

hasPreciseValue

default boolean hasPreciseValue()

Returns:

true if value represented by this SV is precisely known.

inverse

@Nullable
default Constraint inverse()

isValidWith

default boolean isValidWith(@Nullable
                            Constraint constraint)

copyOver

@Nullable
default Constraint copyOver(RelationalSymbolicValue.Kind kind)

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

Parameters:

kind - kind of relation over which constraint is copied

Returns:

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