1. trait AsyncJSEnv extends JSEnv

   

2. trait AsyncJSRunner extends AnyRef

   

3. trait ComJSEnv extends AsyncJSEnv

   

   An AsyncJSEnv that provides communication to and from the JS VM.

   An AsyncJSEnv that provides communication to and from the JS VM.

   Inside the VM there is a global JavaScript object named scalajsCom that can be used to control the message channel. It's operations are:

   // initialize com (with callback)
   scalajsCom.init(function(msg) { console.log("Received: " + msg); });
   
   // send a message to host system
   scalajsCom.send("my message");
   
   // close com (releases callback, allowing VM to terminate)
   scalajsCom.close();

4. trait ComJSRunner extends AsyncJSRunner

   

5. abstract class ExternalJSEnv extends AsyncJSEnv

   

6. trait JSConsole extends AnyRef

   

   Trait representing a JS console

7. trait JSEnv extends AnyRef

   

8. trait JSRunner extends AnyRef

   

9. final class RetryingComJSEnv extends ComJSEnv

   

   A RetryingComJSEnv allows to automatically retry if a call to the underlying ComJSRunner fails.

   A RetryingComJSEnv allows to automatically retry if a call to the underlying ComJSRunner fails.

   While it protects the JVM side from observing state that differs inbetween runs that have been retried, it assumes that the executed JavaScript code does not have side-effects other than the ones visible through the channel (e.g. writing to a file). It is the users responsibility to ensure this property.

   No retrying is performed for synchronous, or normal asynchronous runs.

10. final class VirtualFileMaterializer extends AnyRef

    

    A helper class to temporarily store virtual files to the filesystem.

    A helper class to temporarily store virtual files to the filesystem.

    Can be used with tools that require real files.
