Member Function Documentation
◆ accept()
|
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 320 of file qgssqlstatement.h.
◆ clone()
|
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 400 of file qgssqlstatement.cpp.
◆ dump()
|
overridevirtual |
Abstract virtual dump method.
- Returns
- A statement which represents this node as string
Implements QgsSQLStatement::Node.
Definition at line 369 of file qgssqlstatement.cpp.
◆ leftAssociative()
| bool QgsSQLStatement::NodeBinaryOperator::leftAssociative | ( | ) | const |
Is left associative ?
Definition at line 334 of file qgssqlstatement.cpp.
◆ nodeType()
|
inlineoverridevirtual |
Abstract virtual that returns the type of this node.
- Returns
- The type of this node
Implements QgsSQLStatement::Node.
