Constructor & Destructor Documentation

◆ NodeColumnRef() [1/2]

QgsSQLStatement::NodeColumnRef::NodeColumnRef	(	const QString &	name,
		bool	star
	)

inline

Constructor with column name only.

Definition at line 534 of file qgssqlstatement.h.

◆ NodeColumnRef() [2/2]

QgsSQLStatement::NodeColumnRef::NodeColumnRef	(	const QString &	tableName,
		const QString &	name,

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 556 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 505 of file qgssqlstatement.cpp.

◆ cloneThis()

QgsSQLStatement::NodeColumnRef * QgsSQLStatement::NodeColumnRef::cloneThis ( ) const

Clone with same type return.

Definition at line 510 of file qgssqlstatement.cpp.

◆ distinct()

bool QgsSQLStatement::NodeColumnRef::distinct ( ) const

inline

Whether this is prefixed by DISTINCT.

Definition at line 551 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 491 of file qgssqlstatement.cpp.

◆ name()

QString QgsSQLStatement::NodeColumnRef::name ( ) const

inline

The name of the column.

Definition at line 545 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 553 of file qgssqlstatement.h.

◆ setDistinct()

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

inline

Sets whether this is prefixed by DISTINCT.

Definition at line 539 of file qgssqlstatement.h.

◆ star()

bool QgsSQLStatement::NodeColumnRef::star ( ) const

inline

Whether this is the * column.

Definition at line 548 of file qgssqlstatement.h.

◆ tableName()

QString QgsSQLStatement::NodeColumnRef::tableName ( ) const

inline

The name of the table. May be empty.

Definition at line 542 of file qgssqlstatement.h.
