cz.vutbr.web.domassign.Analyzer

cz.vutbr.web.domassign.DirectAnalyzer

public class DirectAnalyzer
extends Analyzer

A simple ananalyzer that computes a style for the individual DOM nodes with no mapping and caching. This analyzer is suitable for obtaining the style of individual elements without computing the style for the whole DOM tree. However, in larger scale, the performance of the individual computation is significantly worse.
