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.
