Examples of javax.help.search.SearchQuery

javax.help.search.SearchQuery
The instance of a query on a search database. It is instantiated by SearchEngine.startQuery. Subclasses of SearchQuery can perform the search or negotiate the search results with an outside agent as setup in the SearchEngine class. A server search engine is an an example of an outside agent. Search results are returned through SearchEvents to listeners that register with a SearchEngine instance. @author Roger D.
