Detailed Description

The KDbUnaryExpression class represents unary expression (with a single argument).

operation: + - NOT (or !) ~ "IS NULL" "IS NOT NULL"

Definition at line 300 of file KDbExpression.h.

Constructor & Destructor Documentation

◆ KDbUnaryExpression() [1/3]

KDbUnaryExpression::KDbUnaryExpression ( )

Constructs a null unary expression.

See also
KDbExpression::isNull()

Definition at line 186 of file KDbUnaryExpression.cpp.

◆ KDbUnaryExpression() [2/3]

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() [3/3]

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 204 of file KDbUnaryExpression.cpp.

Member Function Documentation

◆ arg()

KDbExpression KDbUnaryExpression::arg ( ) const
Returns
expression that is argument for this unary expression

Definition at line 218 of file KDbUnaryExpression.cpp.

◆ setArg()

void KDbUnaryExpression::setArg ( const KDbExpression arg)

Sets expression argument expr for this unary expression.

Definition at line 223 of file KDbUnaryExpression.cpp.
