WorkbenchContentProvider
public WorkbenchContentProvider()
- Creates the resource content provider.
dispose
public void dispose()
-
Description copied from interface:
IContentProvider
- 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.
-
-
Specified by:
-
dispose
in interface
IContentProvider
-
Overrides:
-
dispose
in class
BaseWorkbenchContentProvider
-
inputChanged
public void inputChanged(
Viewer viewer,
Object oldInput,
Object newInput)
-
Description copied from interface:
IContentProvider
- 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.

does not have an input
resourceChanged
public final void resourceChanged(
IResourceChangeEvent event)
-
Description copied from interface:
IResourceChangeListener
- Notifies this listener that some resource changes
are happening, or have already happened.
The supplied event gives details. This event object (and the
resource delta within it) is valid only for the duration of
the invocation of this method.
Note: This method is called by the platform; it is not intended
to be called directly by clients.
Note that during resource change event notification, further changes
to resources may be disallowed.
