org.apache.olingo.odata2.api.ep.entry.ODataEntry
Interface {@link ExpressionVisitor} is used to traverse a $filter or $orderby expression tree.Any class instance implementing this interface can be passed to the method {@link Visitable#accept(ExpressionVisitor)} of an expression node to start the traversing. While traversing, theappropriate methods of the visitor implementation will be called.
