Class SystemSortableSelection

java.lang.Object
  org.eclipse.rse.ui.SystemSortableSelection

All Implemented Interfaces:

Comparable

public class SystemSortableSelection

extends Object

implements Comparable

The TreeViewer widget does not seem to guarantee that multiple-selections are returned sorted in order of appearance in the tree. Some action require they be, such as MoveUp and MoveDown. This class captures the information for each selected item and permits sorting via position, using the Arrays helper class in java.util.

Constructor for SystemSortableSelection

Method Summary

int	compareTo(Object other)
boolean	equals(Object other)
int	getPosition() Get the poisition of the selected object within its parent list
Object	getSelectedObject() Get the selected object
static Object[]	getSortedObjects(SystemSortableSelection[] sortedArray, Object[] outputArray) IF YOU HAVE CALLED SETPOSITION ON EACH ITEM IN THE GIVEN ARRAY, AND CALLED SORTARRAY, THIS CONVERTS INTO A SORTED ARRAY THAT JUST HAS THE ORIGINAL OBJECTS IN IT FROM THE SELECTION LIST.
static SystemSortableSelection[]	makeSortableArray(IStructuredSelection selection) Convert structured selection into an array of these objects.
void	setPosition(int position) Set the position of the selected object within its parent list
static void	sortArray(SystemSortableSelection[] sortableArray) IF YOU HAVE CALLED SETPOSITION ON EACH ITEM IN THE GIVEN ARRAY, THIS WILL SORT THAT ARRAY BY THE POSITION

makeSortableArray

public static SystemSortableSelection[] makeSortableArray(IStructuredSelection selection)

IF YOU HAVE CALLED SETPOSITION ON EACH ITEM IN THE GIVEN ARRAY, THIS WILL SORT THAT ARRAY BY THE POSITION

getSortedObjects
