      • isFiltered

        public static boolean isFiltered​(Object element)

        Returns whether or not the given object should be filtered out. This applies to any user assistance component's elements where filters apply (e.g. help tocs, topics, intro elements, context help topics). If the element is null or is not filterable, this method returns false.

        This method is for use in non-UI environments, when serving help outside the workbench. If filtering from the UI, use the isFiltered method that accepts the evaluation context as well.

        Parameters:
        element - the element to check
        Returns:
        whether or not the element should be filtered out
      • isFiltered

        public static boolean isFiltered​(Object element,
                                         IEvaluationContext context)

        Returns whether or not the given object should be filtered out. This applies to any user assistance component's elements where filters apply (e.g. help tocs, topics, intro elements, context help topics).

        Parameters:
        element - the element to check
        context - the evaluation context for evaluating expressions
        Returns:
        whether or not the element should be filtered out
