Summary

Ancestor of all URL grabbers

Pascal

 run\JvUrlListGrabber.pas
 TJvCustomUrlGrabber = class(TJvComponent);


Description

This class is the ancestor of all the Url Grabbers and declares the required methods that a grabber must provide. Do not instantiate a TJvUrlGrabber directly, simply use one of its descendants. This family of classes is used by TJvUrlListGrabber to allow downloading a list of URLs. When deriving a new class from this one, please remember that you have to provide implementations for GetDefaultPropertiesClass and GetSupportedURLName. Further, unless you intentionally want to do blocking grabbing, you must create a new class derived from TJvCustomUrlGrabberThread that will handle the grabbing in a separate background thread.
