Class ScrollSweepPlanner

java.lang.Object

com.shaft.gui.browser.internal.ScrollSweepPlanner

public final class ScrollSweepPlanner
extends Object

Pure decision logic for BrowserActions.scrollToLoadAll()'s bounded progressive scroll sweep (issue #3749, Increment D).

Extracted out of the browser-driving loop so the step-count/height-stability stop condition can be unit tested without a real WebDriver, following the same test-seam philosophy as BidiNetworkActivitySource's injected clock.

Method Details

shouldStop

public static boolean shouldStop(int completedSteps,
 int maxSteps,
 long previousPageHeight,
 long currentPageHeight,
 boolean bottomReached)

Decides whether a bounded progressive scroll sweep should stop after the step that just completed.

Stops when either the configured step ceiling has been reached (bounding worst-case cost regardless of page behavior), or the page has stopped growing and the viewport bottom has been reached. A grown page keeps the sweep going even past the visual bottom, since newly appended content may still need one more step to itself be scrolled into view.

Parameters:

completedSteps - number of scroll steps performed so far (including the one that just completed)

maxSteps - the configured ceiling (timeouts.lazyLoadingScrollSweepMaxSteps)

previousPageHeight - the page's scroll height before this step

currentPageHeight - the page's scroll height after this step

bottomReached - whether the viewport bottom reached the page's scroll height after this step

Returns:

true when the sweep should stop
