Member Function Documentation

◆ copy()

ConstExpr * ConstExpr::copy ( ) const
virtual
Returns
a deep copy of this object.

Implements KexiDB::BaseExpr.

Reimplemented in KexiDB::QueryParameterExpr.

Definition at line 484 of file expression.cpp.

◆ debugString()

TQString ConstExpr::debugString ( )
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 525 of file expression.cpp.

◆ getQueryParameters()

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 552 of file expression.cpp.

◆ toString()

TQString 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.

Definition at line 531 of file expression.cpp.

◆ type()

Field::Type ConstExpr::type ( )
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 489 of file expression.cpp.

◆ validate()

bool ConstExpr::validate ( ParseInfo &  parseInfo)
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 557 of file expression.cpp.
