| <section name="Invoking a script"> |
| |
| <p> |
| For invoking a script you have two options - either you invoke the |
| script directly using the ScriptService or you can use a ScriptRunnable |
| (which relies on the ScriptService). |
| </p> |
| |
| <subsection name="Using the ScriptService"> |
| <p> |
| This example invokes a script called "CompilableInterface" and |
| passed two parameters for executing the script. |
| </p> |
| <source> |
| <![CDATA[ |
| Object result = null; |
| SimpleNamespace args = new SimpleNamespace(); |
| args.put("count",new Integer(i)); |
| args.put("currentTime",new Long(System.currentTimeMillis())); |
| result = scriptService.eval("CompilableInterface", args); |
| ]]> |
| </source> |
| </subsection> |
| |
| <subsection name="Using the ScriptRunnable"> |
| <p> |
| This example creates a ScriptRunnable to invoke a |
| script called "MultiThreaded". |
| </p> |
| <source> |
| <![CDATA[ |
| Hashtable args = new Hashtable(); |
| args.put("foo", new Double(0)); |
| ScriptRunnable runnable = scriptService.createRunnable( scriptService, "MultiThreaded", args ); |
| runnable.run(); |
| result = runnable.getResult(); |

| <section name="Accessing Avalon Infrastructure from within a script"> |
| <p> |
| The Fulcrum Script Service passes a ScriptAvalonContext to the script |
| </p> |
| <source> |
| <![CDATA[ |
| var logger = avalonContext.getLogger(); |
| var applicationDir = avalonContext.getApplicationDir(); |
| var tempDir = avalonContext.getTempDir(); |
| var serviceManager = avalonContext.getServiceManager(); |
| var parameters = avalonContext.getParameters(); |
| var configuration = avalonContext.getConfiguration(); |
| var isDebug = configuration.getChild("isDebug").getValueAsBoolean(false); |
| serviceManager.lookup("org.apache.fulcrum.script.ScriptService").exists("Avalon"); |
