goog.db.Cursor

Adds an event listener to the event target. The same handler can only be added once per the type. Even if you add the same handler multiple times using the same type then it will only be called once when the event is dispatched.

Invokes a callback function when this object is disposed. Callbacks are invoked in the order in which they were added. If a callback is added to an already disposed Disposable, it will be called immediately.

Dispatches an event (or event like object) and calls all listeners listening for events of this type. The type of the event is decided by the type property on the event object.

If any of the listeners returns false OR calls preventDefault then this function will return false. If one of the capture listeners calls stopPropagation, then the bubble listeners won't fire.

Disposes of the object and its resources.

Removes listeners from this object. Classes that extend EventTarget may need to override this method in order to remove references to DOM Elements and additional listeners.

Fires all registered listeners in this listenable for the given type and capture mode, passing them the given eventObject. This does not perform actual capture/bubble. Only implementors of the interface should be using this.

Gets the goog.events.ListenableKey for the event or null if no such listener is in use.

Gets all listeners in this listenable for the given type and capture mode.

Returns the parent of this event target to use for capture/bubble mechanism.

NOTE(chrishenry): The name reflects the original implementation of custom event target (goog.events.EventTarget). We decided that changing the name is not worth it.

Whether there is any active listeners matching the specified signature. If either the type or capture parameters are unspecified, the function will match on the remaining criteria.

Adds an event listener. A listener can only be added once to an object and if it is added again the key for the listener is returned. Note that if the existing listener is a one-off listener (registered via listenOnce), it will no longer be a one-off listener after a call to listen().

Adds an event listener that is removed automatically after the listener fired once.

If an existing listener already exists, listenOnce will do nothing. In particular, if the listener was previously registered via listen(), listenOnce() will not turn the listener into a one-off listener. Similarly, if there is already an existing one-off listener, listenOnce does not modify the listeners (it is still a once listener).

Advances the cursor to the next position along its direction. When new data is available, the NEW_DATA event will be fired. If the cursor has reached the end of the range it will fire the COMPLETE event. If opt_key is specified it will advance to the key it matches in its direction.

This wraps the native #continue method on the underlying object.

Associates a disposable object with this object so that they will be disposed together.

Deletes the value at the cursor's position, without changing the cursor's position. Once the value is deleted, the cursor's value is set to null.

Removes all listeners from this listenable. If type is specified, it will only remove listeners of the particular type. otherwise all registered listeners will be removed.

Removes an event listener from the event target. The handler must be the same object as the one added. If the handler has not been added then nothing is done.

Sets the parent of this event target to use for capture/bubble mechanism.

Sets the target to be used for event.target when firing event. Mainly used for testing. For example, see goog.testing.events.mixinListenable.

Removes an event listener which was added with listen() or listenOnce().

Removes an event listener which was added with listen() by the key returned by listen().

Updates the value at the current position of the cursor in the object store. If the cursor points to a value that has just been deleted, a new value is created.

If monitoring the goog.Disposable instances is enabled, stores the creation stack trace of the Disposable instance.

Opens a value cursor from IDBObjectStore or IDBIndex over the specified key range. Returns a cursor object which is able to iterate over the given range.
