public interface EMFFormsDatabinding

EMFFormsDatabinding provides a databinding service. It provides four methods for getting an IValueProperty or an IListProperty from a VDomainModelReference and getting an IObservableValue or an IObservableList from a VDomainModelReference and an EObject.

Method Detail

getObservableValue

org.eclipse.core.databinding.observable.value.IObservableValue getObservableValue(VDomainModelReference domainModelReference,
                                                                                  org.eclipse.emf.ecore.EObject object)
                                                                           throws DatabindingFailedException

Returns an IObservableValue by observing the value described by the given VDomainModelReference of the given EObject.

Parameters:

domainModelReference - The domain model reference pointing to the desired value

object - The root object of the rendered form. If the VDomainModelReference contains a path, the object is the first node of the path. Therefore, the IObservableValue can be bound to a feature of a sub element in case of a path.

Returns:

The resulting IObservableValue, does not return null.

Throws:

DatabindingFailedException - if the databinding could not be executed successfully.

getObservableList

org.eclipse.core.databinding.observable.list.IObservableList getObservableList(VDomainModelReference domainModelReference,
                                                                               org.eclipse.emf.ecore.EObject object)
                                                                        throws DatabindingFailedException

Returns an IObservableList by observing the list described by the given VDomainModelReference of the given EObject.

Parameters:

domainModelReference - The domain model reference pointing to the desired list

object - The root object of the rendered form. If the VDomainModelReference contains a path, the object is the first node of the path. Therefore, the IObservableValue can be bound to a feature of a sub element in case of a path.

Returns:

The resulting IObservableList, does not return null

Throws:

DatabindingFailedException - if the databinding could not be executed successfully.

getValueProperty

org.eclipse.core.databinding.property.value.IValueProperty getValueProperty(VDomainModelReference domainModelReference,
                                                                            org.eclipse.emf.ecore.EObject object)
                                                                     throws DatabindingFailedException

Returns an IValueProperty described by the given VDomainModelReference.

Parameters:

domainModelReference - The domain model reference pointing to the desired value

object - The root object of the rendered form. If the VDomainModelReference contains a path, the object is the first node of the path. Therefore, the IValueProperty can be bound to a feature of a sub element in case of a path.

Returns:

The resulting IValueProperty, does not return null.

Throws:

DatabindingFailedException - if the databinding could not be executed successfully.

getListProperty

org.eclipse.core.databinding.property.list.IListProperty getListProperty(VDomainModelReference domainModelReference,
                                                                         org.eclipse.emf.ecore.EObject object)
                                                                  throws DatabindingFailedException

Returns an IListProperty described by the given VDomainModelReference.

Parameters:

domainModelReference - The domain model reference pointing to the desired list

object - The root object of the rendered form. If the VDomainModelReference contains a path, the object is the first node of the path. Therefore, the IValueProperty can be bound to a feature of a sub element in case of a path.

Returns:

The resulting IListProperty, does not return null.

Throws:

DatabindingFailedException - if the databinding could not be executed successfully.
