virtual void QgsSQLStatement::NodeColumnSorted::accept ( 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.

bool QgsSQLStatement::NodeColumnSorted::ascending ( ) const
inline

Whether the column is sorted in ascending order.

Definition at line 625 of file qgssqlstatement.h.

QgsSQLStatement::Node * QgsSQLStatement::NodeColumnSorted::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 683 of file qgssqlstatement.cpp.

QgsSQLStatement::NodeColumnSorted * QgsSQLStatement::NodeColumnSorted::cloneThis ( ) const

Clone with same type return.

Definition at line 688 of file qgssqlstatement.cpp.

NodeColumnRef* QgsSQLStatement::NodeColumnSorted::column ( ) const
inline

The name of the column.

Definition at line 622 of file qgssqlstatement.h.

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

Abstract virtual dump method.

Returns
A statement which represents this node as string

Implements QgsSQLStatement::Node.

Definition at line 674 of file qgssqlstatement.cpp.

virtual NodeType QgsSQLStatement::NodeColumnSorted::nodeType ( ) const
inlineoverridevirtual

Abstract virtual that returns the type of this node.

Returns
The type of this node
