WindowReference
class WindowReference : JSONAble
A reference to a javascript window/frame existing within a WebView.
This reference is only a pointer to data held within the javascript context of a given WebView. It may no longer be valid the next time you attempt to use it. For instance the page could be navigated away from. There is not much you can use an WindowReference for in Java, it exists primarily to pass back to a WebView for further action.
