Class: QgsExpressionNodeBinaryOperator

class qgis.core.QgsExpressionNodeBinaryOperator

Bases: QgsExpressionNode

A binary expression operator, which operates on two values.

QgsExpressionNodeBinaryOperator(op: QgsExpressionNodeBinaryOperator.BinaryOperator, opLeft: QgsExpressionNode, opRight: QgsExpressionNode) Binary combination of the left and the right with op.
