Base classes

NodeColumnRef(const QString& name, bool star): Constructor with column name only.
NodeColumnRef(const QString& tableName, const QString& name, bool star): Constructor with table and column name.

void accept(QgsSQLStatement::Visitor& v) const override: Support the visitor pattern.
auto clone() const -> QgsSQLStatement::Node* override: Generate a clone of this node.
auto cloneThis() const -> QgsSQLStatement::NodeColumnRef*: Clone with same type return.
auto distinct() const -> bool: Whether this is prefixed by DISTINCT.
auto dump() const -> QString override: Abstract virtual dump method.
auto name() const -> QString: The name of the column.
auto nodeType() const -> QgsSQLStatement::NodeType override: Abstract virtual that returns the type of this node.
void setDistinct(bool distinct = true): Sets whether this is prefixed by DISTINCT.
auto star() const -> bool: Whether this is the * column.
auto tableName() const -> QString: The name of the table. May be empty.

Support the visitor pattern.

Parameters
v	A visitor that visits this node.

For any implementation this should look like

C++:

v.visit( *this );

Python:

v.visit( self)

Generate a clone of this node.

Returns	a deep copy 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.

Abstract virtual dump method.

Returns	A statement which represents this node as string

Abstract virtual that returns the type of this node.

Returns	The type of this node
