notEmpty () : Boolean
Returns true if self contains at least one element - otherwise, returns false.
| Expression | Result |
|---|---|
| Sequence{2, 'a'}->notEmpty() | true |
| Sequence{null}->notEmpty() | true |
| Sequence{}->notEmpty() | false |
Warning!
Never use ->notEmpty on a value type. The value will be converted to a list (with the value as its only item) and that will always evaluate to True.
