count

public int count()

hasMoreElements

public boolean hasMoreElements()

Specified by:

hasMoreElements in interface java.util.Enumeration

nextElement

public java.lang.Object nextElement()

Specified by:

nextElement in interface java.util.Enumeration

nextResult

public SearchEngineResult nextResult()

run

public void run()

Description copied from class: Crawler

Start crawling. Returns either when the crawl is done, or when pause() or stop() is called. Because this method implements the java.lang.Runnable interface, a crawler can be run in the background thread.

Overrides:

run in class Crawler

visit

public void visit(Page page)

Description copied from class: Crawler

Callback for visiting a page. Default version does nothing.

Overrides:

visit in class Crawler

Following copied from class: websphinx.Crawler

Parameters:

page - Page retrieved by the crawler

shouldVisit

public boolean shouldVisit(Link link)

Description copied from class: Crawler

Callback for testing whether a link should be traversed. Default version returns true for all links. Override this method for more interesting behavior.

Overrides:

shouldVisit in class Crawler

Following copied from class: websphinx.Crawler

Parameters:

l - Link encountered by the crawler

Returns:

true if link should be followed, false if it should be ignored.

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

concat

static java.lang.String concat(java.lang.String[] args,
                               int start)
