Method Detail

asBool

public VarBool asBool()

Description copied from class: AbstractConstraint

This method returns a Var variable that is equal 1 if the constraint is satisfied and equals 0 if it is violated. Each constraint that participates in logical expressions should implement this method.

Specified by:

asBool in interface Constraint

Overrides:

asBool in class AbstractConstraint

Returns:

a VarBool variable that is equal to 0

post

public void post()

Description copied from class: AbstractConstraint

This method takes a constraint's implementation and uses its own RI-specific post-method.

Specified by:

post in interface Constraint

Overrides:

post in class AbstractConstraint
