Member Function Documentation

void QgsSQLStatement::NodeColumnSorted::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.

bool QgsSQLStatement::NodeColumnSorted::ascending ( ) const

inline

Whether the column is sorted in ascending order.

Definition at line 685 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.
