Constructor Detail

StructuredContentProvider

public StructuredContentProvider()
Method Detail

dispose

public void dispose()
Description copied from interface: org.eclipse.jface.viewers.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

getInput

public INPUT getInput()

getViewer

public StructuredViewer getViewer()

inputChanged

public void inputChanged(Viewer viewer,
                         Object oldInput,
                         Object newInput)
Description copied from interface: org.eclipse.jface.viewers.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.

Specified by:
inputChanged in interface IContentProvider
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
