Member Function Documentation

accept()

void QgsSQLStatement::NodeJoin::accept ( QgsSQLStatement::Visitor &  v ) const

inlineoverridevirtual

Support the visitor pattern.

For any implementation this should look like

v.visit( *this );

v.visit(self)

Parameters

v	A visitor that visits this node.

Implements QgsSQLStatement::Node.

clone()

QgsSQLStatement::Node * QgsSQLStatement::NodeJoin::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.
