ViewModelContext
This returns the childContext for the provided EObject and the provided VElement
. If a child context
already exists it will be returned otherwise a new ViewModelContext
will be created.
Note that the injection of viewModelServices
is useful for
services that are not registered externally (via extension point or OSGi). If any of these
services locally override registered implementations of the same interface, then it is better
to use a ViewModelServiceProvider
that can propagate the override to child contexts.
