| /** |
| * A tagging interface to share a concrete participant instance across |
| * multiple elements to be refactored. Consider the example of moving |
| * more than one file: if a corresponding move participant is not |
| * tagged as a <code>ISharableParticipant</code> then a separate instance |
| * of a participant is created for every file to be moved. If the |
| * participant is marked as shared then only one instance is created |
| * and the participant is responsible to handle all files to be moved. |
| * <p> |
| * The first element to be refactored will be added to the participant |
| * via the participant specific <code>initialize(Object element)</code> |
| * method. All subsequent elements will be added via the generic <code> |
| * addElement(Object, RefactoringArguments)</code> method. Implementors |
| * of this interface can assume that the refactoring arguments passed |
| * to the <code>addElement</code> method conform to the participant. For |
| * example the arguments are of type <code>MoveArguments</code> if this |
| * interface is mixed into a move participant. |
| * </p> |
| * <p> |
| * Clients may implement this interface to tag participants as shared. |
