StartsWithPredicate

public StartsWithPredicate()

Method Detail

getName

public String getName()

Description copied from interface: PredicateIF

INTERNAL: Returns the name of the predicate. This will usually be the name of the predicate within its module ('instance-of', '/=', 'starts-with'), but some virtual predicates cannot be reached from the syntax and may return names that will not parse.

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.

satisfy

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

Throws:

InvalidQueryException

getCost

public int getCost(boolean[] boundparams)

Description copied from interface: PredicateIF
