Constructor & Destructor Documentation

◆ KDbUnaryExpression() [1/5]

KDbUnaryExpression::KDbUnaryExpression ( )

Constructs a null unary expression.

See also

Definition at line 186 of file KDbUnaryExpression.cpp.

◆ KDbUnaryExpression() [2/5]

KDbUnaryExpression::KDbUnaryExpression ( KDbToken token,
const KDbExpression & arg )

Constructs unary expression with token token and argument arg.

Definition at line 192 of file KDbUnaryExpression.cpp.

◆ KDbUnaryExpression() [3/5]

KDbUnaryExpression::KDbUnaryExpression ( const KDbUnaryExpression & expr)

Constructs a copy of other unary expression expr. Resulting object is not a deep copy but rather a reference to the object expr.

Definition at line 198 of file KDbUnaryExpression.cpp.

◆ KDbUnaryExpression() [5/5]

KDbUnaryExpression::KDbUnaryExpression ( const ExplicitlySharedExpressionDataPointer & ptr)

Definition at line 209 of file KDbUnaryExpression.cpp.

Member Function Documentation

◆ arg()

Definition at line 218 of file KDbUnaryExpression.cpp.

◆ setArg()

void KDbUnaryExpression::setArg ( const KDbExpression & arg)

Sets expression argument expr for this unary expression.
