Throws:

InvalidQueryException

collectionToOne

public static QueryMatches collectionToOne(QueryMatches matches,
 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. So for each row in the input result, either remove it (if it's of the wrong type, or if it has no new object) or insert the new object in the toix column.

generateFromCollection

public static QueryMatches generateFromCollection(QueryMatches matches,
 int fromix,
 int toix,
 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.

filterClass

public static QueryMatches filterClass(QueryMatches matches,
 int ix1,
 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 Collection getAllObjects(TopicMapIF topicmap)

Returns all topic map objects in the topic map.

compare

public static int compare(Object o1,
 Object o2)
