◆ accept()

void QgsSQLStatement::NodeLiteral::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 505 of file qgssqlstatement.h.

◆ clone()

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

Definition at line 462 of file qgssqlstatement.cpp.

◆ nodeType()

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

Abstract virtual that returns the type of this node.

Returns
The type of this node

Implements QgsSQLStatement::Node.

Definition at line 502 of file qgssqlstatement.h.

◆ value()

QVariant QgsSQLStatement::NodeLiteral::value ( ) const
inline
