monitor
- the progress monitor provided by the operation historyinfo
- the adaptable provided by the operation history
- Returns:
- the result of the execution

ExecutionException
- if, for some reason, I fail to complete
the operation
canExecute
public boolean canExecute()
- Checks that the feature is a modifiable feature of the element whose
value will be set by this command. Also checks that the new value is of
the correct type for the feature.
