public java.util.List<IItemPropertyDescriptor> getPropertyDescriptors(java.lang.Object object)
ItemProviderAdapterIItemPropertySource.getPropertyDescriptors
by returning the locally stored vector of descriptors.
This vector could be populated in the constructor of a derived class
but it's probably more efficient to create them only on demand by overriding this method.
You'll probably want to call super.getPropertyDescriptors if you do this,
since you may have one adapter derive from another.

ItemProviderAdaptergetChildren, 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.

Most things really should have an icon, but not having one is technically correct too.

ItemProviderAdapterIItemLabelProvider.getText by simply calling toString on the argument.
This will often be correct as is.

descriptors. Typically, CommandParameters
will be used as descriptors. 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.
