UnaryExpr::UnaryExpr ( int token,
BaseExpr * arg )

Definition at line 212 of file expression.cpp.

◆ UnaryExpr() [2/2]

UnaryExpr::UnaryExpr ( const UnaryExpr & expr)

Definition at line 221 of file expression.cpp.

◆ ~UnaryExpr()

Member Function Documentation

◆ arg()

BaseExpr * KexiDB::UnaryExpr::arg ( ) const
inline

Definition at line 161 of file expression.h.

◆ copy()

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

Implements KexiDB::BaseExpr.

Definition at line 234 of file expression.cpp.

◆ debugString()

TQString UnaryExpr::debugString ( )
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 239 of file expression.cpp.

◆ getQueryParameters()

void UnaryExpr::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.

Definition at line 262 of file expression.cpp.

◆ toString()

TQString UnaryExpr::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.

Definition at line 247 of file expression.cpp.

◆ type()

Field::Type UnaryExpr::type ( )
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 268 of file expression.cpp.

◆ validate()

bool UnaryExpr::validate ( ParseInfo & parseInfo)
virtual
Todo
compare types... e.g. NOT applied to Text makes no sense...

Reimplemented from KexiDB::BaseExpr.

Definition at line 286 of file expression.cpp.
