Member Function Documentation

◆ accept()

void QgsSQLStatement::NodeSelect::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

v	A visitor that visits this node.

Implements QgsSQLStatement::Node.
