Constructor Detail

DynamicOccurrencePredicate

public DynamicOccurrencePredicate(TopicMapIF topicmap,
                                  LocatorIF base,
                                  TopicIF type)

Method Detail

getSignature

public java.lang.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,
                            java.lang.Object[] arguments)
                     throws InvalidQueryException

Throws:

InvalidQueryException
