Interface SequentialUnit

All Superinterfaces:

EObject, ModelElement, MultiUnit, NamedElement, Notifier, Unit

All Known Implementing Classes:

SequentialUnitImpl

public interface SequentialUnit
extends MultiUnit

A representation of the model object 'Sequential Unit'.

Sequential units apply contained transformation units (including rules) sequentially. The application order is given by the position in the list returned by MultiUnit.getSubUnits().

The default behavior is as follows: each unit is applied one after the other. If a unit cannot be applied, the sequential units aborts, rolls back all changes of this sequential unit and returns false (indicates non-successful application). Otherwise true is returned.

This behavior can be altered slightly using attributes strict and rollback. The defaults are strict=true and rollback=true with the semantics described above. If strict=false, even inapplicable rules/units will not break the sequential application order, i.e., all containees are tried to be applied one after the other. Consequently, unstrict sequential units are always successful. If rollback=false no rollback is performed on aborts.

The following features are supported:

• Strict
• Rollback
