Method Summary | |
protected void |
collectNewChildDescriptors(Collection newChildDescriptors,
Object object)
This adds to newChildDescriptors , a collection of CommandParameter s, parameters for
possible children of the specified object , when viewed as
an instance of the type for which this is an item provider. |
protected List |
getAllConcreteSubclasses(EClass eClass)
|
protected List |
getAllEClasses(EClass eClass)
|
protected Collection |
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 . |
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(Object object)
This looks up the name of the type of the specified object. |
void |
notifyChanged(Notification notification)
Does nothing; clients may override so that it does something. |

getChildren
, including in determining whether to cache children and, if so, in setting up the store. It is also
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.

newChildDescriptors
, a collection of CommandParameter
s, 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.
