@Deprecated
public interface AtomicLockListener
extends EventListener

Listener for begining and end of the atomic locking. It can be used to optimize the document listeners if a large amounts of edits are performed in an atomic change. For example if there's a timer restarted after each document modification to update an external pane showing the document structure after 2000ms past the last modification occurred then there could be a following listener used:

  class MultiListener implements DocumentListener, AtomicLockListener {

    private boolean atomic; // whether in atomic change

    public void insertUpdate(DocumentEvent evt) {
      modified(evt);
    }

    public void removeUpdate(DocumentEvent evt) {
      modified(evt);
    }

    public void changedUpdate(DocumentEvent evt) {
    }

    private void modified(DocumentEvent evt) {
      if (!atomic) {
        restartTimer(); // restart the timer
      }
    }

    public void atomicLock(AtomicLockEvent evt) {
      atomic = true;
    }

    public void atomicUnlock(AtomicLockEvent evt) {
      atomic = false;
    }

  }
