Method Summary

static QueryMatches	collectionToOne(QueryMatches matches, java.lang.Object[] objects, int fromix, int toix, int operation) Given a collection of objects, produce a single new object from each of them and put it into the toix column.
static int	compare(java.lang.Object o1, java.lang.Object o2)
static QueryMatches	filter(QueryMatches matches, int ix1, int ix2, java.lang.Class class1, java.lang.Class class2, int operation)
static QueryMatches	filterClass(QueryMatches matches, int ix1, java.lang.Class klass) Filters a result set so that only rows where the object in a specific column is an instance of a specific class are accepted.
static QueryMatches	generateFromCollection(QueryMatches matches, int fromix, int toix, java.util.Collection startset, int operation) Assuming both columns are empty, iterate over a collection of start values, binding the first column to the start value, and the second column to each object in a collection generated from the start value.
static java.util.Collection	getAllObjects(TopicMapIF topicmap) Returns all topic map objects in the topic map.
static QueryMatches	objectToMany(QueryMatches matches, int fromix, int toix, java.lang.Class fromclass, int operation, IndexIF index)
static QueryMatches	objectToMany(QueryMatches matches, int fromix, int toix, java.lang.Class fromclass, int operation, IndexIF index1, IndexIF index2)
static QueryMatches	objectToOne(QueryMatches matches, int fromix, int toix, java.lang.Class fromclass, int operation)

                                                  int operation)

Assuming both columns are empty, iterate over a collection of start values, binding the first column to the start value, and the second column to each object in a collection generated from the start value.

public static QueryMatches filterClass(QueryMatches matches,
                                       int ix1,
                                       java.lang.Class klass)

Filters a result set so that only rows where the object in a specific column is an instance of a specific class are accepted.

getAllObjects

public static java.util.Collection getAllObjects(TopicMapIF topicmap)

Returns all topic map objects in the topic map.

compare

public static int compare(java.lang.Object o1,
                          java.lang.Object o2)
