Member Function Documentation

accept()

void QgsSQLStatement::NodeColumnRef::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 547 of file qgssqlstatement.h.

clone()

QgsSQLStatement::Node * QgsSQLStatement::NodeColumnRef::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 524 of file qgssqlstatement.cpp.

cloneThis()

QgsSQLStatement::NodeColumnRef * QgsSQLStatement::NodeColumnRef::cloneThis

(

)

const

Clone with same type return.

Definition at line 529 of file qgssqlstatement.cpp.

distinct()

bool QgsSQLStatement::NodeColumnRef::distinct ( ) const

inline

Whether this is prefixed by DISTINCT.

Definition at line 542 of file qgssqlstatement.h.

dump()

QString QgsSQLStatement::NodeColumnRef::dump ( ) const

overridevirtual

Abstract virtual dump method.

Returns

A statement which represents this node as string

Implements QgsSQLStatement::Node.

Definition at line 510 of file qgssqlstatement.cpp.

name()

QString QgsSQLStatement::NodeColumnRef::name ( ) const

inline

The name of the column.

Definition at line 536 of file qgssqlstatement.h.

nodeType()

QgsSQLStatement::NodeType QgsSQLStatement::NodeColumnRef::nodeType ( ) const

inlineoverridevirtual

Abstract virtual that returns the type of this node.

Returns

The type of this node

Implements QgsSQLStatement::Node.

Definition at line 544 of file qgssqlstatement.h.

setDistinct()

void QgsSQLStatement::NodeColumnRef::setDistinct ( bool  distinct = true )

inline

Sets whether this is prefixed by DISTINCT.

Definition at line 530 of file qgssqlstatement.h.

star()

bool QgsSQLStatement::NodeColumnRef::star ( ) const

inline

Whether this is the * column.

Definition at line 539 of file qgssqlstatement.h.

tableName()

QString QgsSQLStatement::NodeColumnRef::tableName ( ) const

inline

The name of the table. May be empty.

Definition at line 533 of file qgssqlstatement.h.
