Class DynamicFailurePredicate

java.lang.Object

net.ontopia.topicmaps.query.impl.basic.AbstractDynamicPredicate

net.ontopia.topicmaps.query.impl.basic.DynamicFailurePredicate

All Implemented Interfaces:

BasicPredicateIF, PredicateIF

Direct Known Subclasses:

DynamicFailurePredicate

public class DynamicFailurePredicate
extends AbstractDynamicPredicate

INTERNAL: Special predicate used when a topic is used as a predicate but the topic is neither an association type nor an occurrence type. It is needed because creating a DynamicAssociationPredicate or DynamicOccurrencePredicate assumes a particular type of parameter (pair or non-pair), whereas this predicate will not complain about that.

Method Detail

getSignature

public String getSignature()

Description copied from interface: PredicateIF

INTERNAL: Returns a string representing the signature of the predicate. The string consists of a whitespace-separated list of arguments, where each argument is made up of tokens representing the type or cardinality of that argument.

The instance-of predicate would have a signature of "t t", while /= would have ". .", and in would have ". .+". For full details, see topicmaps.impl.utils.ArgumentValidator.

getCost

public int getCost(boolean[] boundparams)

Description copied from interface: PredicateIF

INTERNAL.

satisfy

public QueryMatches satisfy(QueryMatches matches,
                            Object[] arguments)
                     throws InvalidQueryException

Throws:

InvalidQueryException
