Job job= new SearchForEmployessJob();
job.setJobGroup(jobGroup);
job.schedule();

13. IStructuredSelection from
StructuredViewers
TreeViewer treeViewer = new TreeViewer(parent);
ISelection selection =
treeViewer.getSelection();
if(selection instanceof IStructuredSelection) {
IStructuredSelection structuredSelection =
(IStructuredSelection) selection;
}
TreeViewer treeViewer = new TreeViewer(parent);
ITreeSelection structuredSelection =
treeViewer.getStructuredSelection();
TableViewer tableViewer = new TableViewer(parent);
IStructuredSelection selection =
tableViewer.getStructuredSelection();
