public class StyleExpressionsEvaluator
extends AbstractElementFormatFunction
implements StructureFunction

Evaluates style-expressions and updates the stylesheet. This is an internal helper function. It is not meant to be used by end-users and manually adding this function to a report will cause funny side-effects.
