Defines how the underlying resource of this ChangeSetMember can be completed (comitted)

cancel

void cancel()

Defines how the underlying resource of this ChangeSetMember can be cancelled (rolled back)

isMarkedForCancel

boolean isMarkedForCancel()

Defines, if the underlying resource of this ChangeSetMember was requested to be cancelled (rolled back). Please note that usually a ChangeSetContext is marked for cancel as a whole through ChangeSetContext.markForCancel() This method is mainly intended if there is some other (outside) API available, that could set the cancellation marker on the underlying resource.

Returns:

true, if the underlying resource was marked for cancellation through some (outside) API.
