Continue

Indicates that the new value is accepted and that the change processing chain should continue to completion.

Cancel

Indicates that the new value is NOT accepted and that the change processing chain should be canceled. No further processing will occur.

Reverse

Indicates that the new value is NOT accepted. Unlike the Cancel action, however, abort causes the existing value to be re-applied to the infodriver slot, effectively reverting any change. In most cases cancel should be used but there may be circumstances, such as when some parts of the system may already have been notified of the change, where reverse is more appropriate to return the slot to its previous state.
