Examples of org.apache.cayenne.exp.Expression.traverse()

org.apache.cayenne.exp.Expression.traverse()
Traverses itself and child expressions, notifying visitor via callback methods as it goes. This is an Expression-specific implementation of the "Visitor" design pattern. @since 1.1

            // ObjEntity.getAttribute may return a decorator for attribute on
            // each call, resulting in dupes
            final Map<String, ObjAttribute> attributes = new HashMap<String, ObjAttribute>();
            final DbEntity dbEntity = descriptor.getEntity().getDbEntity();


            qualifier.traverse(new TraversalHelper() {


                @Override
                public void startNode(Expression node, Expression parentNode) {
                    if (node.getType() == Expression.DB_PATH) {
                        String path = node.getOperand(0).toString();
