Examples of com.caucho.es.Script

com.caucho.es.Script
The Script object represents a compiled JavaScript. Executing it is thread safe. To create a Script, use the Parser class to parse a file.
Java programs set JavaScript Global properties by adding objects to a HashMap. Typically you will at least assign the 'File' and the 'out' objects. The running script will see these objects as properties of the Global object. If you set the 'out' object, the script can use the bare bones 'writeln("foo")' to write to 'out'.
```
 HashMap map = new HashMap(); map.put("File", Vfs.lookup()); map.put("out", System.out); map.put("myObject", myObject); script.execute(map, null); 
```
You can also make any Java object be the global prototype. Essentially, the effect is similar to the HashMap technique, but it's a little simpler.
Scripts are thread-safe. Multiple script instances can safely execute in separate threads. Script.execute creates the entire JavaScript global object hierarchy fresh for each execution. So one Script execution cannot interfere with another, even by doing evil things like modifying the Object prototype.
Of course, wrapped Java objects shared by script invocations must still be synchronized.
