ResourceItemProvider(AdapterFactory adapterFactory)
This constructs an instance from a factory and a notifier. |
Method Summary | |
---|---|
protected void |
collectNewChildDescriptors(java.util.Collection<java.lang.Object> newChildDescriptors,
java.lang.Object object)
This adds CommandParameter s describing the children
that can be created under this object. |
java.util.Collection<?> |
getChildren(java.lang.Object object)
This implements ITreeItemContentProvider.getChildren . |
java.util.Collection<? extends EStructuralFeature> |
getChildrenFeatures(java.lang.Object object)
This specifies how to implement getChildren(java.lang.Object) and is used to deduce an appropriate feature for an
AddCommand , RemoveCommand or
MoveCommand in createCommand . |
java.lang.Object |
getImage(java.lang.Object object)
This returns Resource.gif. |
java.util.Collection<?> |
getNewChildDescriptors(java.lang.Object object,
EditingDomain editingDomain,
java.lang.Object sibling)
This implements IEditingDomainItemProvider.getNewChildDescriptors , returning descriptors for all the possible children that
can be added to the specified object . |
java.lang.Object |
getParent(java.lang.Object object)
This returns the parent of the Resource. |
java.util.List<IItemPropertyDescriptor> |
getPropertyDescriptors(java.lang.Object object)
This returns the property descriptors for the adapted class. |
ResourceLocator |
getResourceLocator()
Return the resource locator for this item provider's resources. |
java.lang.String |
getText(java.lang.Object object)
This returns the label text for the adapted class. |
void |
notifyChanged(Notification notification)
This handles notification by calling fireNotifyChanged . |

ItemProviderAdapter
ITreeItemContentProvider.getChildren
. If children are
already cached in a ItemProviderAdapter.ChildrenStore
, they are returned. Otherwise, children are collected from the features
returned by getChildrenFeatures
. The collected children may or may not be cached,
depending on the result of createChildrenStore
; by default, no store is returned if
getChildrenFeatures
returns only containment references. All children are optionally
wrapped
before being cached and returned. Subclasses may override createWrapper
to specify when and with what to wrap children.

ItemProviderAdapter
IEditingDomainItemProvider.getNewChildDescriptors
, returning descriptors for all the possible children that
can be added to the specified object
. Usually, these descriptors will be instances of
CommandParameter
s, containing at least the child object and the feature
under which it should be added.
This implementation invokes collectNewChildDescriptors
, which should be
overridden by derived classes, to build this collection.
If sibling
is non-null, an index is added to each CommandParameter
with a multi-valued
feature, to ensure that the new child object gets added in the right position.
