QString FunctionExpr::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).
