Description copied from class: FilterDirective

Return one of RES_INCLUDE, RES_EXCLUDE or RES_INGORE to indicate how to filter the row. RES_INCLUDE means that the row should be included in the resurt except when negation if query is desired. RES_EXCLUDE is the opposite, row is not included except in the case of negation. RES_IGNORE means that row is not included regardless of query being evaluated in negation mode or not. This can be because for example the association doesn't have the assumed players.

Throws:

TopicMapException
