Method Detail

createViewModelContext

public ViewModelContext createViewModelContext(VElement view,
                                               org.eclipse.emf.ecore.EObject domainObject)

Instantiates a new view model context.

Parameters:

view - the view

domainObject - the domain object

Returns:

the created ViewModelContext

createViewModelContext

public ViewModelContext createViewModelContext(VElement view,
                                               org.eclipse.emf.ecore.EObject domainObject,
                                               ViewModelService... modelServices)

Instantiates a new view model context with specific services. Note that this 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.

Parameters:

view - the view

domainObject - the domain object

modelServices - an array of services to use in the ViewModelContext

Returns:

the created ViewModelContext

createViewModelContext

public ViewModelContext createViewModelContext(VElement view,
                                               org.eclipse.emf.ecore.EObject domainObject,
                                               ViewModelServiceProvider serviceProvider)

Instantiates a new view model context with a provider of local service overrides. The serviceProvider is propagated to child contexts to override registered services in their scope, too.

Parameters:

view - the view

domainObject - the domain object

serviceProvider - a provider of local view-model services to override any statically registered services of the same types. May be null if local service overrides are not needed

Returns:

the created ViewModelContext

1.16

createViewModelContext

public ViewModelContext createViewModelContext(VElement view,
                                               org.eclipse.emf.ecore.EObject domainObject,
                                               java.util.Map<java.lang.String,?> contextValues)

Instantiates a new view model context with initial context values. The serviceProvider is propagated to child contexts to override registered services in their scope, too.

Parameters:

view - the view

domainObject - the domain object

contextValues - initial context values to set

Returns:

the created ViewModelContext

Since:

1.21

                                               org.eclipse.emf.ecore.EObject domainObject,
                                               ViewModelServiceProvider serviceProvider,
                                               java.util.Map<java.lang.String,?> contextValues)

Instantiates a new view model context with a provider of local service overrides and initial context values. The serviceProvider is propagated to child contexts to override registered services in their scope, too.

Parameters:

view - the view

domainObject - the domain object

serviceProvider - a provider of local view-model services to override any statically registered services of the same types. May be null if local service overrides are not needed

contextValues - initial context values to set

Returns:

the created ViewModelContext

Since:

provide

public static ViewModelServiceProvider provide(ViewModelService... modelServices)

Obtain a view-model service provider that statically provides a set of services.

Parameters:

modelServices - model services to provider

Returns:

the static provider of those services
