Constructor & Destructor Documentation

◆ NodeInOperator()

QgsSQLStatement::NodeInOperator::NodeInOperator ( QgsSQLStatement::Node node,
QgsSQLStatement::NodeList list,
bool  notin = false 
)
inline

Constructor.

◆ ~NodeInOperator()

QgsSQLStatement::NodeInOperator::~NodeInOperator ( )
inlineoverride

Definition at line 400 of file qgssqlstatement.h.

Member Function Documentation

◆ accept()

void QgsSQLStatement::NodeInOperator::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
vA visitor that visits this node.

Implements QgsSQLStatement::Node.

Definition at line 414 of file qgssqlstatement.h.

◆ clone()

QgsSQLStatement::Node * QgsSQLStatement::NodeInOperator::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 431 of file qgssqlstatement.cpp.

◆ dump()

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

Abstract virtual dump method.

Returns
A statement which represents this node as string

Implements QgsSQLStatement::Node.

Definition at line 426 of file qgssqlstatement.cpp.

◆ isNotIn()

bool QgsSQLStatement::NodeInOperator::isNotIn ( ) const
inline

Whether this is a NOT IN operator.

Definition at line 406 of file qgssqlstatement.h.

◆ list()

QgsSQLStatement::NodeList* QgsSQLStatement::NodeInOperator::list ( ) const
inline

Values list.

Definition at line 409 of file qgssqlstatement.h.

◆ node()

QgsSQLStatement::Node* QgsSQLStatement::NodeInOperator::node ( ) const
inline

Variable at the left of IN.

Definition at line 403 of file qgssqlstatement.h.

◆ nodeType()

QgsSQLStatement::NodeType QgsSQLStatement::NodeInOperator::nodeType ( ) const
inlineoverridevirtual

Abstract virtual that returns the type of this node.

Returns
The type of this node

Implements QgsSQLStatement::Node.

Definition at line 411 of file qgssqlstatement.h.
