default VView getView(org.eclipse.emf.ecore.EObject object,
                      VViewModelProperties properties)

Retrieve a VView for a domain model object without any required filter keys.

Specified by:

getView in interface EMFFormsViewService

Parameters:

object - the domain model object for which a view is to be requested

properties - the properties for providing the view, that may or may not include matching filters

Returns:

a view model for the given domain model object or null if no suitable provider could be found to provide one

getView

VView getView(org.eclipse.emf.ecore.EObject object,
              VViewModelProperties properties,
              java.util.Collection<java.lang.String> requiredKeys)

Retrieve a VView for a domain model object from the most confident of my registered view providers.

Parameters:

object - the domain model object for which a view is to be requested

properties - the properties for providing the view, that may or may not include matching filters

requiredKeys - a subset (possibly empty) of the keys in the properties that must be matched by any view model that I would provide. If any of these keys does not match a view model, then that view model must not be provided. Otherwise, it may just be less preferred than some other view model that does match

Returns:

a view model for the given domain model object or null if no suitable provider could be found to provide one
