Constructor & Destructor Documentation

◆ NodeUnaryOperator()

QgsSQLStatement::NodeUnaryOperator::NodeUnaryOperator ( QgsSQLStatement::UnaryOperator  op,
QgsSQLStatement::Node operand 
)
inline

Constructor.

Member Function Documentation

◆ accept()

void QgsSQLStatement::NodeUnaryOperator::accept ( QgsSQLStatement::Visitor v) const
inlineoverridevirtual

Support the visitor pattern.

For any implementation this should look like

C++:

v.visit( *this );

Python:

v.visit( self)
Parameters
vA visitor that visits this node.

Implements QgsSQLStatement::Node.

Definition at line 340 of file qgssqlstatement.h.

◆ clone()

QgsSQLStatement::Node * QgsSQLStatement::NodeUnaryOperator::clone ( ) const
overridevirtual

Generate a clone of this node.

Make sure that the clone does not contain any information which is generated in prepare and context related. Ownership is transferred to the caller.

Returns
a deep copy of this node.

Implements QgsSQLStatement::Node.

Definition at line 301 of file qgssqlstatement.cpp.

◆ dump()

QString QgsSQLStatement::NodeUnaryOperator::dump ( ) const
overridevirtual

Abstract virtual dump method.

Returns
A statement which represents this node as string

Implements QgsSQLStatement::Node.

Definition at line 296 of file qgssqlstatement.cpp.

◆ nodeType()

QgsSQLStatement::NodeType QgsSQLStatement::NodeUnaryOperator::nodeType ( ) const
inlineoverridevirtual

Abstract virtual that returns the type of this node.

Returns
The type of this node

Implements QgsSQLStatement::Node.

Definition at line 337 of file qgssqlstatement.h.

◆ op()

QgsSQLStatement::UnaryOperator QgsSQLStatement::NodeUnaryOperator::op ( ) const
inline

Operator.

Definition at line 332 of file qgssqlstatement.h.

◆ operand()

QgsSQLStatement::Node* QgsSQLStatement::NodeUnaryOperator::operand ( ) const
inline

Operand.

Definition at line 335 of file qgssqlstatement.h.
