void NArgExpr::getQueryParameters ( QuerySchemaParameterList & params ) [virtual]

Collects query parameters (messages and types) reculsively and saves them to params. The leaf nodes are objects of QueryParameterExpr class.

QString NArgExpr::toString ( QuerySchemaParameterValueListIterator * params = 0 ) [virtual]

Returns:
string as a representation of this expression element by running recursive calls. param, if not 0, points to a list item containing value of a query parameter (used in QueryParameterExpr).
