QgsExpressionNode

Abstract base class for all nodes that can appear in an expression.

Methods

evalNode
isNotIn	Returns True if this node is a "NOT IN" operator, or False if the node is a normal "IN" operator.
list	Returns the list of nodes to search for matching values within.
node	Returns the expression node.

class qgis.core.QgsExpressionNodeInOperator

Bases: QgsExpressionNode

__init__(node: QgsExpressionNode | None, list: QgsExpressionNode.NodeList | None, 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.

Parameters:

• node (Optional[QgsExpressionNode])

• list (Optional[QgsExpressionNode.NodeList])

• notin (bool = False)

__init__(a0: QgsExpressionNodeInOperator)

Parameters:

a0 (QgsExpressionNodeInOperator)

evalNode(self, parent: QgsExpression | None, context: QgsExpressionContext | None) → Any

Parameters:

• parent (Optional[QgsExpression])

• context (Optional[QgsExpressionContext])

Return type:

Any

isNotIn(self) → bool

Returns True if this node is a “NOT IN” operator, or False if the node is a normal “IN” operator.

Return type:

bool

list(self) → QgsExpressionNode.NodeList | None

Returns the list of nodes to search for matching values within.

Return type:

Optional[QgsExpressionNode.NodeList]

node(self) → QgsExpressionNode | None

Returns the expression node.

Return type:

Optional[QgsExpressionNode]

prepareNode(self, parent: QgsExpression | None, context: QgsExpressionContext | None) → bool

Parameters:

• parent (Optional[QgsExpression])

• context (Optional[QgsExpressionContext])

Return type:

bool
