| QString ConstExpr::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).
Implements KexiDB::BaseExpr.

| void ConstExpr::getQueryParameters | ( | QuerySchemaParameterList & | params | ) | [virtual] |
Collects query parameters (messages and types) reculsively and saves them to params. The leaf nodes are objects of QueryParameterExpr class.
