Member Function Documentation

accept()

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.

Definition at line 689 of file qgssqlstatement.h.

ascending()

bool QgsSQLStatement::NodeColumnSorted::ascending ( ) const

inline

Whether the column is sorted in ascending order.

Definition at line 684 of file qgssqlstatement.h.

clone()

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 696 of file qgssqlstatement.cpp.

cloneThis()

QgsSQLStatement::NodeColumnSorted * QgsSQLStatement::NodeColumnSorted::cloneThis

(

)

const

Clone with same type return.

Definition at line 701 of file qgssqlstatement.cpp.

column()

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

inline

The name of the column.

Definition at line 681 of file qgssqlstatement.h.

dump()

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 687 of file qgssqlstatement.cpp.

nodeType()

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

inlineoverridevirtual

Abstract virtual that returns the type of this node.

Returns

The type of this node
