public class WCMFilteringResourceWrapper
extends FilteringResourceWrapper

Filters child resources of the given resource based on the given contentResource design properties The current wrapper is filtering child resources using Granite ExpressionResolver It does that by adding custom variables to the ExpressionCustomizer which will use the request as a data vessel. Later the ExpressionResolver via its CustomVariableELResolver will read the registered custom variables to resolve the granite:hide expression. That expression can then refer to the custom variables
