Method Detail

enforce

public ConstraintResult enforce(ConstraintStore constraintStore)

Description copied from interface: Constraint

Attempts to enforce this constraint using the given ConstraintStore.

Specified by:

enforce 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

reify

public ConstraintResult reify(ReadConstraintStore constraintStore)

Specified by:

reify in interface Constraint

walk

public void walk(java.util.function.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 Implication replace(java.util.function.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 java.lang.String toString()

Overrides:

toString in class java.lang.Object
