public boolean mayHaveChildren()
Element
interface. This implementation always
returns true
.
mayHaveChildren
in interface Element
mayHaveChildren
in class Node
true
if this Element
may contain
child Element
s.Element.mayHaveChildren()
public java.util.Iterator getChildren()
Element
interface. This implementation returns
an Iterator
over the current list of children.
getChildren
in interface Element
getChildren
in class Node
Iterator
over any child Element
s
contained by this Element
. If there are no children,
null
is returned.Element.getChildren()
public boolean canAdd(Element element)
Folder
interface. The default implementation
returns true
if and only if the specified
Element
is not null
.
canAdd
in interface Folder

- the Element
that is about to be added
to this Folder
.
true
if and only if the specified

Element
is null
, this method does nothing.No notification is fired by this method.
