  - fetchDataAsync
```
public abstract ListenableFuture<InputStream> fetchDataAsync()
```
    Executes an asynchronous operation to fetch the item data. The result is an InputStream object. You are responsible for closing the InputStream after using it.
    Returns:
    
    a ListenableFuture for tracking when the operation is done and getting the result; also allows cancellation. Calling get() on the returned future may throw an ExecutionException with its cause set to an exception as follows:
    
    IOException if the data cannot be fetched
    
    Since:
    
    100.0.0
  - fetchThumbnailAsync
```
public abstract ListenableFuture<byte[]> fetchThumbnailAsync()
```
    Executes an asynchronous operation to fetch the thumbnail for the item. The result is a byte[] containing the thumbnail data, or null if there is no thumbnail for the item.
    Returns:
    
    a ListenableFuture for tracking when the operation is done and getting the result; also allows cancellation. Calling get() on the returned future may throw an ExecutionException with its cause set to an exception as follows:
    
    IOException if the thumbnail cannot be fetched
    
    Since:
    
    100.0.0
  - updateItemPropertiesAsync
```
public abstract ListenableFuture<Void> updateItemPropertiesAsync()
```
    Executes an asynchronous operation to update any item properties that have been changed (using the setter methods). This causes the values that have been changed to be updated on the portal (for PortalItems) or on disk (for LocalItems).
    Updating properties can be only done for local items that are unpacked. For example, a mobile map package file (.mmpk) can be unpacked using MobileMapPackage.unpackAsync(String, String). Once unpacked, local items within the package can be updated see MobileMapPackage.getItem() and for any maps use GeoModel.getItem(). As well as packages, the local item available from an item resource cache can be updated. This is accessed with ItemResourceCache.getItem().
    
    Returns:
    
    a ListenableFuture for tracking when the operation is done and getting the result; also allows cancellation
    
    Since:
    
    100.4.0
