Method Summary
|
void
|
dispose
()
Disposes of this content provider. |
void
|
inputChanged
(
Viewer viewer,
Object oldInput,
Object newInput)
Notifies this content provider that the given viewer's input
has been switched to a different element. |
dispose
void dispose()
- Disposes of this content provider.
This is called by the viewer when it is disposed.
The viewer should not be updated during this call, as it is in the process
of being disposed.
-
inputChanged
void inputChanged(
Viewer viewer,
Object oldInput,
Object newInput)
- Notifies this content provider that the given viewer's input
has been switched to a different element.
A typical use for this method is registering the content provider as a listener
to changes on the new input (using model-specific means), and deregistering the viewer
from the old input. In response to these change notifications, the content provider
should update the viewer (see the add, remove, update and refresh methods on the viewers).
The viewer should not be updated during this call, as it might be in the process
of being disposed.

Parameters:
-
viewer - the viewer -
oldInput - the old input element, or null if the viewer
did not previously have an input -
newInput - the new input element, or null if the viewer
does not have an input
