Member Function Documentation

◆ accept()

void QgsSQLStatement::NodeBinaryOperator::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 380 of file qgssqlstatement.h.

◆ clone()

QgsSQLStatement::Node * QgsSQLStatement::NodeBinaryOperator::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 437 of file qgssqlstatement.cpp.

◆ dump()

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

Abstract virtual dump method.

Returns
A statement which represents this node as string

Implements QgsSQLStatement::Node.

Definition at line 406 of file qgssqlstatement.cpp.

◆ leftAssociative()

bool QgsSQLStatement::NodeBinaryOperator::leftAssociative ( ) const

Is left associative ?

Definition at line 371 of file qgssqlstatement.cpp.

◆ nodeType()

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

Abstract virtual that returns the type of this node.

Returns
The type of this node

Implements QgsSQLStatement::Node.

Definition at line 377 of file qgssqlstatement.h.

◆ op()

QgsSQLStatement::BinaryOperator QgsSQLStatement::NodeBinaryOperator::op ( ) const
inline

Operator.

Definition at line 369 of file qgssqlstatement.h.

◆ opLeft()

QgsSQLStatement::Node* QgsSQLStatement::NodeBinaryOperator::opLeft ( ) const
inline

Left operand.

Definition at line 372 of file qgssqlstatement.h.

◆ opRight()

QgsSQLStatement::Node* QgsSQLStatement::NodeBinaryOperator::opRight ( ) const
inline

Right operand.

Definition at line 375 of file qgssqlstatement.h.

◆ precedence()

int QgsSQLStatement::NodeBinaryOperator::precedence ( ) const

Precedence.

Definition at line 326 of file qgssqlstatement.cpp.
