Examples of org.jboss.dna.graph.query.model.NodeDepth

org.jboss.dna.graph.query.model.NodeDepth
A dynamic operand that evaluates to the depth of a node given by a selector, used in a {@link Comparison} constraint.

            SelectorName replacement = rewrittenSelectors.get(value.getSelectorName());
            if (replacement == null) return operand;
            return new PropertyValue(replacement, value.getPropertyName());
        }
        if (operand instanceof NodeDepth) {
            NodeDepth depth = (NodeDepth)operand;
            SelectorName replacement = rewrittenSelectors.get(depth.getSelectorName());
            if (replacement == null) return operand;
            return new NodeDepth(replacement);
        }
        if (operand instanceof NodePath) {
            NodePath path = (NodePath)operand;
            SelectorName replacement = rewrittenSelectors.get(path.getSelectorName());
            if (replacement == null) return operand;
