Member Function Documentation

void QgsSQLStatement::NodeUnaryOperator::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 335 of file qgssqlstatement.h.

QgsSQLStatement::Node * QgsSQLStatement::NodeUnaryOperator::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 294 of file qgssqlstatement.cpp.

QString QgsSQLStatement::NodeUnaryOperator::dump ( ) const

overridevirtual

Abstract virtual dump method.

Returns

A statement which represents this node as string

Implements QgsSQLStatement::Node.

Definition at line 289 of file qgssqlstatement.cpp.

QgsSQLStatement::NodeType QgsSQLStatement::NodeUnaryOperator::nodeType ( ) const

inlineoverridevirtual

Abstract virtual that returns the type of this node.

Returns

The type of this node

Implements QgsSQLStatement::Node.
