| /** |
| * Adds an event listener that listens for the specified <code>eventTypes</code> (a combination of one or more |
| * event types encoded as a bit mask value). |
| * <p> |
| * The set of events can be filtered by specifying restrictions based on characteristics of the node associated |
| * with the event. In the case of event types <code>NODE_ADDED</code> and <code>NODE_REMOVED</code>, the node |
| * associated with an event is the node at (or formerly at) the path returned by <code>Event.getPath</code>. |
| * In the case of event types <code>PROPERTY_ADDED</code>, <code>PROPERTY_REMOVED</code> and |
| * <code>PROPERTY_CHANGED</code>, the node associated with an event is the parent node of the property at |
| * (or formerly at) the path returned by <code>Event.getPath</code>: |
| * <ul> |
| * <li> |
| * <code>absPath</code>, <code>isDeep</code>: Only events whose associated node is at |
| * <code>absPath</code> (or within its subtree, if <code>isDeep</code> is <code>true</code>) will be received. |
| * It is permissible to register a listener for a path where no node currently exists. |
| * </li> |
| * <li> |
| * <code>uuid</code>: Only events whose associated node has one of the UUIDs in this list will be |
| * received. If his parameter is <code>null</code> then no UUID-related restriction is placed on events |
| * received. |
| * </li> |
| * <li> |
| * <code>nodeTypeName</code>: Only events whose associated node has one of the node types |
| * (or a subtype of one of the node types) in this list will be received. If his parameter is |
| * <code>null</code> then no node type-related restriction is placed on events received. |
| * </li> |
| * </ul> |
| * The restrictions are "ANDed" together. In other words, for a particular node to be "listened to" it must meet all the restrictions. |
| * <p> |
| * Additionally, if <code>noLocal</code> is <code>true</code>, then events generated by the session through which |
| * the listener was registered are ignored. Otherwise, they are not ignored. |
| * <p> |
| * The filters of an already-registered <code>EventListener</code> can be changed at runtime by re-registering the |
| * same <code>EventListener</code> object (i.e. the same actual Java object) with a new set of filter arguments. |
| * The implementation must ensure that no events are lost during the changeover. |
| * |
| * @param listener an {@link EventListener} object. |
| * @param eventTypes A combination of one or more event type constants encoded as a bitmask. |
| * @param absPath an absolute path. |
| * @param isDeep a <code>boolean</code>. |
| * @param uuid array of UUIDs. |
| * @param nodeTypeName array of node type names. |
| * @param noLocal a <code>boolean</code>. |
| * @throws RepositoryException If an error occurs. |

| * executing. An exception to this rule is a listener which deregisters |
