Instance Property

isValid

A Boolean value indicating whether the column is valid.

Declaration

var isValid: Bool { get }

Discussion

You check isValid after an MLUntypedColumn has been created or mutated because none of its initializers, methods, or operators throw an error. For example, comparing two columns of different sizes creates an invalid column.
