Member Function Documentation

QString ConstExpr::debugString (   )  [virtual]
 

Reimplemented from KexiDB::BaseExpr.

Reimplemented in KexiDB::QueryParameterExpr.

Definition at line 482 of file expression.cpp.

References KexiDB::Driver::defaultSQLTypeName(), KexiDB::BaseExpr::tokenToDebugString(), toString(), and type().

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.

Implements KexiDB::BaseExpr.

Reimplemented in KexiDB::QueryParameterExpr.

Definition at line 509 of file expression.cpp.

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.

Reimplemented in KexiDB::QueryParameterExpr.
