public void dispose()
org.eclipse.jface.viewers.IContentProvider
The viewer should not be updated during this call, as it is in the process of being disposed.

public Object[] getChildren(Object parentElement)
org.eclipse.jface.viewers.ITreeContentProvider
The difference between this method and IStructuredContentProvider.getElements
is that getElements
is called to obtain the
tree viewer's root elements, whereas getChildren
is used
to obtain the children of a given parent element in the tree (including a root).
getChildren
in interface ITreeContentProvider
parentElement
- the parent element
public Object[] getElements(Object parentElement)
org.eclipse.jface.viewers.ITreeContentProvider
NOTE: The returned array must not contain the given
inputElement
, since this leads to recursion issues in
AbstractTreeViewer
(see
bug 9262).
getElements
in interface IStructuredContentProvider
getElements
in interface ITreeContentProvider
parentElement
- the input element
public Object getParent(Object element)
org.eclipse.jface.viewers.ITreeContentProvider
null
indicating that the parent can't be computed.
In this case the tree-structured viewer can't expand
a given node correctly if requested.
getParent
in interface ITreeContentProvider
element
- the element
null
if it
has none or if the parent cannot be computedpublic static ComposedAdapterFactory createAdapterFactory()
public boolean hasChildren(Object parentElement)
org.eclipse.jface.viewers.ITreeContentProvider
Intended as an optimization for when the viewer does not
need the actual children. Clients may be able to implement
this more efficiently than getChildren
.
hasChildren
in interface ITreeContentProvider
parentElement
- the element
true
if the given element has children,
and false
if it has no children
