Member Function Documentation
| virtual QString KexiDB::BaseExpr::toString | ( | QuerySchemaParameterValueListIterator * | params = 0 |
) | [pure 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).
Implemented in KexiDB::NArgExpr, KexiDB::UnaryExpr, KexiDB::BinaryExpr, KexiDB::ConstExpr, KexiDB::QueryParameterExpr, KexiDB::VariableExpr, and KexiDB::FunctionExpr.
| virtual void KexiDB::BaseExpr::getQueryParameters | ( | QuerySchemaParameterList & | params | ) | [pure virtual] |
Collects query parameters (messages and types) reculsively and saves them to params. The leaf nodes are objects of QueryParameterExpr class.
Implemented in KexiDB::NArgExpr, KexiDB::UnaryExpr, KexiDB::BinaryExpr, KexiDB::ConstExpr, KexiDB::QueryParameterExpr, KexiDB::VariableExpr, and KexiDB::FunctionExpr.
| QString KexiDB::BaseExpr::tokenToDebugString | ( | ) | [inline] |
- Returns:
- single character if the token is < 256 or token name, e.g. LESS_OR_EQUAL (for debugging).
Definition at line 96 of file expression.h.
| QString BaseExpr::tokenToString | ( | ) | [virtual] |
- Returns:
- string for token, like "<=" or ">"
Reimplemented in KexiDB::BinaryExpr.
Definition at line 108 of file expression.cpp.
| NArgExpr * BaseExpr::toNArg | ( | ) |
Convenience type casts.
