Method Detail

conflictDetectedInAttachesFor

public void conflictDetectedInAttachesFor(int p,
                                          int i)

Specified by:

conflictDetectedInAttachesFor in interface DataStructureFactory<ILits>

Overrides:

conflictDetectedInAttachesFor in class AbstractDataStructureFactory<ILits>

i - the index of the conflicting constraint

getAttachesFor

public IVec<Propagatable> getAttachesFor(int p)

Specified by:

getAttachesFor in interface DataStructureFactory<ILits>

Overrides:

getAttachesFor in class AbstractDataStructureFactory<ILits>

Returns:

a vector containing all the objects to be notified of the satisfaction of that literal.

createClause

public Constr createClause(IVecInt literals)
                    throws ContradictionException

Parameters:

literals - a set of literals using Dimacs format (signed non null integers).

Returns:

null if the constraint is a tautology.

Throws:

ContradictionException - the constraint is trivially unsatisfiable.

createUnregisteredClause

public Constr createUnregisteredClause(IVecInt literals)

createLits

protected ILits createLits()

Specified by:

createLits in class AbstractDataStructureFactory<ILits>
