public final class Scripts
extends Object

Implementations of Fn.Presenters that delegate to Java scripting API. Initialize your presenter like this:

 
 Runnable run = ...; // your own init code
 Fn.Presenter p = Scripts.Scripts.createPresenter();
 BrowserBuilder.newBrowser(p).
      loadFinished(run).
      BrowserBuilder.showAndWait();
 

and your runnable can make extensive use of JavaScriptBody directly or indirectly via APIs using such annotation themselves.

Alternatively one can manipulate the presenter manually, which is especially useful when writing tests:

  @Test public void runInASimulatedBrowser() throws Exception {
   Fn.Presenter p = Scripts.Scripts.createPresenter();
   try (Closeable c = Fn.activate(p)) {
     // your code operating in context of p
   }
 }
 

The previous code snippet requires Java 7 language syntax, as it relies on try-with-resources language syntactic sugar feature. The same block of code can be used on older versions of Java, but it is slightly more verbose.

Method Detail

createPresenter

public static Fn.Presenter createPresenter()

Simple implementation of Fn.Presenter that delegates to Java scripting API. The presenter runs headless without appropriate simulation of browser APIs. Its primary usefulness is inside testing environments. The presenter implements Executor interface, but invokes all runnables passed to Executor.execute(java.lang.Runnable) immediately.

Returns:

new instance of a presenter that is using its own ScriptEngine for text/javascript mimetype

createPresenter

public static Fn.Presenter createPresenter(Executor exc)

Implementation of Fn.Presenter that delegates to Java scripting API and can control execution thread. The presenter runs headless without appropriate simulation of browser APIs. Its primary usefulness is inside testing environments. The presenter implements Executor interface, and passes all runnables from Executor.execute(java.lang.Runnable) to here in provided exc instance.

Parameters:

exc - the executor to re-schedule all asynchronous requests to

Returns:

new instance of a presenter that is using its own ScriptEngine for text/javascript mimetype
