Method Detail

shiftElements

protected void shiftElements(org.eclipse.core.commands.ExecutionEvent event,
                             int positionShift)
                      throws org.eclipse.core.commands.ExecutionException

Shifts selected elements on the specified position shift.

Parameters:

event - the handler execution event, cannot be null

positionShift - element position shift, cannot be 0; positive values means position shift down (closer to list last element) and negative values means position shift up (closer to list first element)

Throws:

org.eclipse.core.commands.ExecutionException - if execution fails with some reason

moveElements

protected void moveElements(org.eclipse.core.commands.ExecutionEvent event,
                            AbstractMoveElementHandler.IListElementIndexComputer newIndexComputer)
                     throws org.eclipse.core.commands.ExecutionException

Moves selected elements according to the provided new index computer.

Parameters:

event - the handler execution event, cannot be null

newIndexComputer - the computer that computes the new index of the element considering the provided all list elements and the selected elements, cannot be null

Throws:

org.eclipse.core.commands.ExecutionException - if execution fails with some reason
