Base classes

QgsExpressionNode

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

Methods

higherBound	Returns the higher bound expression node of the range.
lowerBound	Returns the lower bound expression node of the range.
negate	Returns True if the predicate is an exclusion test (NOT BETWEEN).
node	Returns the expression node.

Virtual Methods

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

class qgis.core.QgsExpressionNodeBetweenOperator

Bases: QgsExpressionNode

__init__(node: QgsExpressionNode | None, nodeLowerBound: QgsExpressionNode | None, nodeHigherBound: QgsExpressionNode | None, negate: bool = False)

This node tests if the result of node is between the result of nodeLowerBound and nodeHigherBound nodes. Optionally it can be inverted with negate which by default is False.

Parameters:

• node (Optional[QgsExpressionNode])

• nodeLowerBound (Optional[QgsExpressionNode])

• nodeHigherBound (Optional[QgsExpressionNode])

• negate (bool = False)

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

Parameters:

• parent (Optional[QgsExpression])

• context (Optional[QgsExpressionContext])

Return type:

Any

higherBound(self) → QgsExpressionNode | None

Returns the higher bound expression node of the range.

Return type:

Optional[QgsExpressionNode]

lowerBound(self) → QgsExpressionNode | None

Returns the lower bound expression node of the range.

Return type:

Optional[QgsExpressionNode]

negate(self) → bool

Returns True if the predicate is an exclusion test (NOT BETWEEN).

Return type:

bool

node(self) → QgsExpressionNode | None

Returns the expression node.

Return type:

Optional[QgsExpressionNode]

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

Parameters:

• parent (Optional[QgsExpression])

• context (Optional[QgsExpressionContext])

Return type:

bool
