Conduit
extends Object
| java.lang.Object | |
| ↳ | android.support.test.espresso.web.bridge.Conduit |
A mechanism to get results out of a Javascript context and into a Java context.
Users can get instances of this class via JavaScriptBridge.makeConduit(). Each conduit can be used once (and only once) to transmit results. Before evaluating javascript via a loadUrl call the caller should call wrapScriptInConduit with the script to be evaluated. The script is wrapped up into an additional handler statement which forwards the result of the script to the JavaScriptBridge object. After calling loadUrl the caller can use the getResult method to get a Future which will contain the result of the javascript execution.
