Kengkaj,
Because this is a hook you could use to set up delegation to some other
factory (by deriving a new class and specializing this method), but by
default here isn't any such delegation.

Hi, Kengkaj,
It sounds like you need to be able to create a TransactionalEditingDomain
with your own adapter factory? The TransactionalEditingDomain.Factory
interface doesn't support that. Perhaps you can raise an enhancement
request to introduce a Factory2 interface that has a create(...) method
with an AdapterFactory parameter?
Thanks,
Christian

Christian,
In the meantime, he could cast the getAdapterFactory to
ComposedAdapterFactory and add factories to it that way or cast the
editing domain to AdapterFactoryEditingDomain to call setAdapterFactory
or even new up a TransactionalEditingDomainImpl and use the constructor...

Thank you Christian. I will raise a request.
Does that means if I want a editing domain deduces parent for RemoveCommand,
or deduces all the children for CopyCommand I must set a AdapterFactory to
editing domain manually?
Before that I thought that after I create a editing domain with
TransactionalEditingDomain.Factory.INSTANCE.createEditingDom ain(), a
AdapterFactory for adapting IEditingDomainItemProvider will be created
automatically.
BTW, I am very appreciate for you help, thank you very much Christian.

Hi, Kengkaj,
Ordinarily, you wouldn't need to set your own adapter factory, anyway,
because the editing domain is currently constructed with the
ComposedAdapterFactory that uses EMF's registry to find all available
adapter factories for metamodels that have registered them.
The most common reason, I suppose, why you might need to set your own
factory would be if you are using a metamodel that hasn't been regenerated
since EMF introduced the adapter factory registry.
Cheers,
Christian
