Class: QgsExpressionNodeInOperator

class qgis.core.QgsExpressionNodeInOperator

Bases: QgsExpressionNode

An expression node for value IN or NOT IN clauses.

QgsExpressionNodeInOperator(node: QgsExpressionNode, list: QgsExpressionNode.NodeList, notin: bool = False) This node tests if the result of node is in the result of list. Optionally it can be inverted with notin which by default is False.
