jez 235f81718d Added Expression_scanner and scan (a visitor pattern basically) to allow XPathExpression_impls to be examined. This is used in the match rewriting to search for position() and last() function calls. ... To ease implementing scan, BinaryExpression and UnaryExpression now inherit XPathExpression_impl. Other classes now derived only from Binary|UnaryExpression rather than from XPathExpression_impl as well.		2007-12-21 15:56:04 +00:00
