Class: QgsExpressionNodeInOperator¶

An expression node for value IN or NOT IN clauses.

List of all members, including inherited members

Class Hierarchy¶

Base classes¶

QgsExpressionNode

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

Methods

`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.

Virtual Methods

In PyQGIS, only methods marked as virtual can be safely overridden in a Python subclass of QgsExpressionNodeInOperator. See the FAQ for more details.

`evalNode`
`prepareNode`

class qgis.core.QgsExpressionNodeInOperator[source]¶

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)

virtual evalNode(self, parent: QgsExpression | None, context: QgsExpressionContext | None) → Any[source]¶

Parameters:

parent (Optional[QgsExpression])
context (Optional[QgsExpressionContext])

Return type:

Any

isNotIn(self) → bool[source]¶

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[source]¶

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

Return type:: Optional[QgsExpressionNode.NodeList]

node(self) → QgsExpressionNode | None[source]¶

Returns the expression node.

Return type:: Optional[QgsExpressionNode]

virtual prepareNode(self, parent: QgsExpression | None, context: QgsExpressionContext | None) → bool[source]¶

Parameters:

parent (Optional[QgsExpression])
context (Optional[QgsExpressionContext])

Return type:

bool
