`getPhantomLayerGraphics( callback) ` | `callback( graphicsLayerJSON)` | Used with offline browser restarts. Returns a JSON representation of the internal phantom graphics layer. This layer is designed to indicate to the user any graphic that has been modified while offline. The appcache-features.html sample demonstrates this pattern.
`addAttachments()` | Internal | Adds an attachment.
`deleteAttachments()` | Internal | Deletes an attachment.
`getUsage(callback)`| `callback({usage}, error)` | **New @ v2.5** Returns the approximate size of the database in bytes. the usage Object is {sizeBytes: number, editCount: number}.
`getPhantomGraphicsArray( callback)` | `callback(boolean, array)` | **New @ v2.5** Used with offline browser restarts. Returns an array of phantom graphics from the database.
`getAllEditsArray(callback)` | `callback(boolean, array)` | **New @ v2.5** Returns an array of all edits stored in the database.
`getFeatureLayerJSON(url,callback)` | `callback( boolean, JSON )` | **New @ v2.5.** Retrieves the feature layer's JSON using `f=json` parameter.
