Class CGatherer 

java.lang.Object

public class CGatherer
extends Object
implements Runnable
Instances of this class spider a single web site. A number of gatherers running in parallel is launched by the search engine (class CSearchEngine). Communication between the search engine and the gatherer threads is done through a stack containing all web sites to be spidered. Each gatherer picks one of these sites' index URLS at a time and spiders all pages belonging to that site. If all sites have been spidered the gatherer threads implicitly terminate.
Each page spidered by a gatherer is parsed and pushed onto another stack. It is task of a higher layer object (in this case the search engine) to do something useful with these pages.
