DynamicAssociationPredicate

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

Method Detail

isRecursive

public boolean isRecursive()

Description copied from interface: JDOPredicateIF

INTERNAL:

Specified by:

isRecursive in interface JDOPredicateIF

prescan

public void prescan(QueryBuilder builder,
                    List arguments)

Description copied from interface: JDOPredicateIF

INTERNAL: This method will be called before building the query. It is used mainly for analyzing the predicate.

Specified by:

prescan in interface JDOPredicateIF

buildQuery

public boolean buildQuery(QueryBuilder builder,
                          List expressions,
                          List arguments)
                   throws InvalidQueryException

buildQuery in interface JDOPredicateIF

Returns:

true if predicate was mapped to JDO expression; false if the predicate could not be mapped to an JDO expression.

Throws:

InvalidQueryException
