Class WebPageHTMLDocumentEventHandler

  • All Implemented Interfaces:
    ai.platon.pulsar.common.lang.ChainedHandler , ai.platon.pulsar.common.lang.PFunction , ai.platon.pulsar.common.lang.PFunction2 , ai.platon.pulsar.common.lang.PHandler 
    
public class WebPageHTMLDocumentEventHandler
extends AbstractChainedFunction2<WebPage, FeaturedDocument, Any>

    An event handler that accepts a WebPage and a FeaturedDocument, anything can be returned.

    The event handler should work with the passed document, such as extracting fields, persisting extraction results, collecting more links, and so on.

    The Web asset might be changed by the handler since WebPage has setters.

    Another possible way to write more robust code is to remove all setters in WebPage, and add a MutableWebPage subclass.
