Constructor & Destructor Documentation

◆ NodeCast()

QgsSQLStatement::NodeCast::NodeCast ( QgsSQLStatement::Node node,
const QString &  type 
)
inline

Constructor.

Member Function Documentation

◆ accept()

void QgsSQLStatement::NodeCast::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 607 of file qgssqlstatement.h.

◆ clone()

QgsSQLStatement::Node * QgsSQLStatement::NodeCast::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 742 of file qgssqlstatement.cpp.

◆ dump()

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

Abstract virtual dump method.

Returns
A statement which represents this node as string

Implements QgsSQLStatement::Node.

Definition at line 732 of file qgssqlstatement.cpp.

◆ node()

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

Node that is referred to.

Definition at line 599 of file qgssqlstatement.h.

◆ nodeType()

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

Abstract virtual that returns the type of this node.

Returns
The type of this node

Implements QgsSQLStatement::Node.

Definition at line 604 of file qgssqlstatement.h.

◆ type()

QString QgsSQLStatement::NodeCast::type ( ) const
inline

Type.

Definition at line 602 of file qgssqlstatement.h.
