public class NotOrStep
- extends GotoStep
Evaluate properties specified by the associated Descriptors, and
transfer control to the specified step if ANY of them are
false
(if boolean) or null (if Object).
This is the exact opposite of OrStep
To avoid non-deterministic evaluation stack behavior, all of the
specified Descriptors are always evaluated.
Supported Attributes:
- step - Identifier of the Step to which control
should be transferred if the condition is met.
