public interface PageEventHandlers

The central interface for managing all event handlers triggered at various stages of a webpage's lifecycle.

PageEventHandlers organizes events into three distinct groups:

LoadEventHandlers - Events during the loading and parsing stage
BrowseEventHandlers - Events during the interactive browsing stage
CrawlEventHandlers - Events in the browser stage (before and after loading)

1.  browser.onWillLoad
2.  load.onNormalize
3.  load.onWillLoad
4.  load.onWillFetch
5.  browse.onWillLaunchBrowser
6.  browse.onBrowserLaunched
7.  browse.onWillFetch
8.  browse.onWillNavigate
9.  browse.onNavigated
10. browse.onWillInteract
11. browse.onWillCheckDocumentState
12. browse.onDocumentFullyLoaded
13. browse.onWillScroll
14. browse.onDidScroll
15. browse.onDocumentSteady         <-- Best for custom RPA actions
16. browse.onWillComputeFeature
17. browse.onFeatureComputed
18. browse.onDidInteract
19. browse.onWillStopTab
20. browse.onTabStopped
21. browse.onFetched
22. load.onFetched
23. load.onWillParse
24. load.onWillParseHTMLDocument
25. load.onHTMLDocumentParsed       <-- Best for data extraction
26. load.onParsed
27. load.onLoaded
28. browser.onLoaded

val handlers = DefaultPageEventHandlers()
handlers.loadEventHandlers.onLoaded.addLast { page ->
    println("Loaded: ${page.url}")
}
val link = ListenableHyperlink(url, args = "-parse", eventHandlers = handlers)
session.submit(link)

val options = session.options("-parse")
options.eventHandlers.browseEventHandlers.onDocumentSteady.addLast { page, driver ->
    driver.click("#button")
}
session.load(url, options)

handlers.le.onLoaded.addLast { page -> }  // loadEventHandlers
handlers.be.onDocumentSteady.addLast { page, driver -> }  // browseEventHandlers
handlers.ce.onWillLoad.addLast { url -> url }  // crawlEventHandlers

DefaultPageEventHandlers - Standard implementation with default behaviors
AbstractPageEventHandlers - Base class for custom implementations

```
 abstract PageEventHandlers chain(PageEventHandlers other)
```
    Chains another page event handler to the tail of this one.
    All handler groups (load, browse, browser) are chained together. Chained handlers execute in order: this handler's callbacks first, then the other handler's callbacks.
    val baseHandlers = DefaultPageEventHandlers() val customHandlers = DefaultPageEventHandlers() customHandlers.le.onLoaded.addLast { page -> println("Custom") } baseHandlers.chain(customHandlers) // Custom handler runs after base
    Parameters:
    
    other - The page event handlers to chain
    
    Returns:
    
    This handler instance for fluent chaining
  - getLoadEventHandlers
```
 abstract LoadEventHandlers getLoadEventHandlers()

```
 abstract BrowseEventHandlers getBrowseEventHandlers()
```
    Event handlers during the browsing stage.
    Controls browser automation: navigation, scrolling, and custom RPA actions.
