Method Detail

getServiceManager

protected ServiceManager getServiceManager()

Needed to get things working with JDK 1.3. Can be removed once we don't support that platform any more.

configure

public void configure(Configuration config)
               throws ConfigurationException

Specified by:

configure in interface Configurable

Overrides:

configure in class AbstractInterpreter

Throws:

ConfigurationException

initialize

public void initialize()
                throws Exception

Specified by:

initialize in interface Initializable

Throws:

Exception

compileScript

protected org.mozilla.javascript.Script compileScript(org.mozilla.javascript.Context cx,
                                                      org.mozilla.javascript.Scriptable scope,
                                                      Source src)
                                               throws Exception

Description copied from class: CompilingInterpreter

TODO - This is a little bit strange, the interpreter calls get Script on the ScriptSourceEntry which in turn calls compileScript on the interpreter. I think we need more refactoring here.

Specified by:

compileScript in class CompilingInterpreter

Throws:

Exception

callFunction

public void callFunction(String funName,
                         List params,
                         Redirector redirector)
                  throws Exception

Calls a JavaScript function, passing params as its arguments. In addition to this, it makes available the parameters through the cocoon.parameters JavaScript array (indexed by the parameter names).

Specified by:

callFunction in interface Interpreter

Parameters:

funName - a String value

params - a List value

redirector -

Throws:

Exception - if an error occurs

handleContinuation

public void handleContinuation(String id,
                               List params,
                               Redirector redirector)
                        throws Exception

Description copied from interface: Interpreter

Continues a previously started processing. The continuation object where the processing should start from is indicated by the continuationId string.

Specified by:

handleContinuation in interface Interpreter

Parameters:

id - a String value

params - a List value, containing the parameters to be passed when invoking the continuation. As opposed to the parameters passed by callFunction, these parameters will only become available in the language's environment, if at all.

redirector - a Redirector used to call views

Throws:

Exception - if an error occurs

forwardTo

public void forwardTo(org.mozilla.javascript.Scriptable scope,
                      FOM_Cocoon cocoon,
                      String uri,
                      Object bizData,
                      FOM_WebContinuation fom_wk,
                      Redirector redirector)
               throws Exception

Throws:
