OCLOperators notEmpty

From MDrivenWiki

notEmpty () : Boolean

Returns true if self contains at least one element, false otherwise.

Expression Result
Sequence{2, 'a'}->notEmpty() true
Sequence{null}->notEmpty() true
Sequence{}->notEmpty() false

Never use ->notEmpty on a value type. The value will be converted to a list (with the value as it's only item) and that will always evaluate to True.
