| * A reconciling strategy is used by an reconciler to reconcile a model |
| * based on text of a particular content type. It provides methods for |
| * incremental as well as non-incremental reconciling. |
| * <p> |
| * If a reconcile strategy consists of several steps between which |
| * model transformation is desired the each step should implement |
| * {@link org.eclipse.jface.text.reconciler.IReconcileStep}. |
| * </p> |
| * <p> |
| * In order to provide backward compatibility for clients of <code>IReconcilingStrategy</code>, extension |
| * interfaces are used to provide a means of evolution. The following extension interfaces exist: |
| * <ul> |
| * <li>{@link org.eclipse.jface.text.reconciler.IReconcilingStrategyExtension} since version 2.0 introducing |
| * the following functions: |
| * <ul> |
| * <li>usage of a progress monitor</li> |
| * <li>initial reconciling step: if a reconciler runs as periodic activity in the background, this |
| * methods offers the reconciler a chance for initializing its strategies and achieving a |
| * reconciled state before the periodic activity starts.</li> |
| * </ul> |
| * </li> |
| * </ul> |
| * </p> |
| * <p> |
| * This interface must be implemented by clients. Implementers should be |
| * registered with a reconciler in order get involved in the reconciling |
| * process. |
