Constructor Details

Between

public Between(Expression e,
 long min,
 long max)

Enforces that the possible values of the given Expression are within the given range (inclusive).

Parameters:

e -

min - the minimum possible value (inclusive) for the expression

max - the maximum possible value (inclusive) for the expression

Method Details

enforce

public ConstraintResult enforce(ConstraintStore m)

Description copied from interface: Constraint

Attempts to enforce this constraint using the given ConstraintStore.

Specified by:

enforce in interface Constraint

reify

public ConstraintResult reify(ReadConstraintStore constraintStore)

Specified by:

reify in interface Constraint

prevent

public ConstraintResult prevent(ConstraintStore constraintStore)

Description copied from interface: Constraint

Attempts to prevent this constraint using the given ConstraintStore.

Specified by:

prevent in interface Constraint

walk

public void walk(Consumer<Expression> r)

Description copied from interface: Constraint

Traverse this constraint.

Specified by:

walk in interface Constraint

Specified by:

walk in interface Expression

Parameters:

r - will be called for each Expression contained within this Constraint.

replace

public Between replace(Function<LeafExpression,LeafExpression> r)

Description copied from interface: Constraint

Returns new Constraint with LeafExpressions in this Constraint replaced with values returned from the given function.

Specified by:

replace in interface Constraint

Specified by:

replace in interface Expression

Parameters:

r - returns the LeafExpression to use as a replacement for the LeafExpression it is called with, or null if the original LeafExpression should continue to be used.

Returns:

a new Constraint with LeafExpressions in this Constraint replaced with versions returned from function.

toString

public String toString()

Overrides:

toString in class Object
