Creates a new JobStatusTableContentProvider.

Parameters:

viewer - the TableViewer to serve

Method Detail

defaultLanguageChanged

public void defaultLanguageChanged(LanguageResourceChangeEvent lrce)

Called whenever the default language changes.

Specified by:

defaultLanguageChanged in interface ILanguageResourceChangeListener

Parameters:

lrce - the triggered LanguageResourceChangeEvent

status - the JobStatus to add

removeJob

public void removeJob(JobStatus status)

Parameters:

status - the JobStatus to remove

getJobStates

public JobStatus[] getJobStates()

Gets all JobStatus objects currently managed by this JobStatusTableContentProvider.

Returns:

the JobStatus objects currently managed by this JobStatusTableContentProvider

getElements

public Object[] getElements(Object inputElement)

Returns the elements to display in the viewer when its input is set to the given element. These elements can be presented as rows in a table, items in a list, etc. The result is not modified by the viewer.

Specified by:

getElements in interface IStructuredContentProvider

Parameters:

inputElement - the input element

Returns:

the array of elements to display in the viewer

See Also:

IStructuredContentProvider.getElements(java.lang.Object)

dispose

public 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.

Specified by:

dispose in interface IContentProvider

See Also:

IContentProvider.dispose()

inputChanged

public 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.

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

See Also:

IContentProvider.inputChanged(org.eclipse.jface.viewers.Viewer, java.lang.Object, java.lang.Object)

createReaper

private void createReaper()

Creates an IdleJobStatusReaper and binds it to this JobStatusTableContentProvider.
