oracle.ide.model.XMLDataContainer
public class XMLDataContainer
The XMLDataContainer
is the Node
wrapper for a Folder
-implementing JavaBean that can be persisted to XML using the XML marshalling framework in oracle.ide.marshal.xml
.
XMLDataContainer
wraps objects that can contain children. In order to interact with XMLDataContainer
, wrapped objects must implement Folder
.
All methods to the XMLDataContainer
's Element
and Folder
methods are forwarded to the wrapped Folder
object.
If the wrapped object is not an instance of Folder
, then an IllegalStateException
will be thrown every time an operation that requires the children list is called.

Element
Element
interface to provide a convenient way of determining whether an object may have children without having to test the object's type with the instanceof
operator or having to downcast to a more specific type.
An implementation of Element
that represents a leaf in a tree structure should return false
from this method. An implementation of Element
that could represent a non-leaf in a tree structure should return true
from this method, even if it does not currently contain any children.
