Class StyleSheetList

All Implemented Interfaces:

public class StyleSheetList extends HtmlUnitScriptable

An ordered list of stylesheets, accessible via document.styleSheets, as specified by the DOM Level 2 Style spec and the Gecko DOM Guide.

If CSS is disabled via WebClientOptions.setCssEnabled(boolean), instances of this class will always be empty. This allows us to check for CSS enablement/disablement in a single location, without having to sprinkle checks throughout the code.
