/**
|
|
* This class implements Rhino-like JavaAdapter to help implement a Java
|
|
* interface in JavaScript. We support this using Invocable.getInterface.
|
|
* Using this JavaAdapter, script author could write:
|
|
*
|
|
*
|
|
* var r = new java.lang.Runnable() {
|
|
* run: function() { script... }
|
|
* };

|
*
|
|
* r.run();
|
|
* new java.lang.Thread(r).start();
|
|
*
|
|
*
|
|
* Note that Rhino's JavaAdapter support allows extending a Java class and/or
|
|
* implementing one or more interfaces. This JavaAdapter implementation does
|
|
* not support these.
