org.eclipse.emf.edit.provider.ItemProviderAdapter
org.eclipse.emf.edit.provider.ReflectiveItemProvider
This adapter implementation provides reflective support that emulates the behaviour of a default generated item provider.

an instance of the type for which this is an item provider. |

getChildrenFeatures(Object object)
If this is defined to be something other than an empty list, it is used to implement getChildren, including in determining whether to cache children and, if so, in setting up the store. |
Object |
getCreateChildImage(Object owner,
Object feature,
Object child,
Collection selection)
This returns the icon image for CreateChildCommand. |
String |
getCreateChildText(Object owner,
Object feature,
Object child,
Collection selection)
This returns the label for CreateChildCommand. |
protected String |
getFeatureText(Object feature)
This looks up the name of the specified feature. |
Object |
getImage(Object object)
This does the same thing as ILabelProvider.getImage, it fetches the label image specific to this object instance. |
protected EStructuralFeature |
getLabelFeature(EClass eClass)
|
List |
getPropertyDescriptors(Object object)
This does the same thing as IPropertySource.getPropertyDescriptors. |
String |
getText(Object object)
This does the same thing as ILabelProvider.getlText, it fetches the label text specific to this object instance. |
protected String |
getTypeText(EAttribute attribute)
This looks up the name of the type of the specified attribute. |
protected String |
getTypeText(Object object)
This looks up the name of the type of the specified object. |
protected boolean |
isWrappingNeeded(Object object)
Returns whether this item provider may need to use wrappers for some or all of the values it returns as children. |
void |
notifyChanged(Notification notification)
Does nothing; clients may override so that it does something. |

used to deduce the appropriate feature for an AddCommand, RemoveCommand or
MoveCommand in createCommand. If you override those methods, then you don't
need to implement this.

ItemProviderAdapternewChildDescriptors, a collection of CommandParameters, parameters for
possible children of the specified object, when viewed as
an instance of the type for which this is an item provider. This
implementation adds nothing to the collection, but derived classes
should override this method, invoking the superclass implementation and
then adding to the collection.

ItemProviderAdapterchildren. This is used to determine whether to use a store to keep track of children and whether to
use command wrappers that re-wrap results and affected objects. The default implementation of createWrapper also tests this method and will not create any wrappers if it returns
false.
This implementation consults getChildrenFeatures, returning true if any feature
map or simple attributes contribute children. This provides backwards compatibility with pre-2.0 subclasses
and enables the more useful new default behaviour for attributes, which were previously not allowed. Subclasses
may override this to enable wrapping of cross-referenced model objects, or to immediately return true
or false, as desired. This is a convenient way to disable all of the new wrapping features in 2.0.
