public class EntityCheckerManagerImpl
extends Object
implements EntityCheckerManager

Parameters:

namespace - URI name space for which the given checker should be used.

checker - the EntityChecker that should be registered for the given URI name space.

checkMarkings

public void checkMarkings(Collection<? extends org.aksw.gerbil.transfer.nif.Marking> markings)

Description copied from interface: EntityCheckerManager

Parameters:

markings - a List of Markings that should be checked for their existence if they implement or contain a Meaning.

checkMeanings

public void checkMeanings(Collection<? extends org.aksw.gerbil.transfer.nif.Meaning> meanings)

Description copied from interface: EntityCheckerManager

Parameters:

meanings - a List of Meanings that should be checked for their existence.
