Method Detail

configure

public void configure(Configuration config)
               throws ConfigurationException

Specified by:

configure in interface Configurable

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,

                                               throws Exception

Description copied from class: CompilingInterpreter

TODO - This is a little bit strange, the interpreter calls CompilingInterpreter.ScriptSourceEntry.compile(org.mozilla.javascript.Context, org.mozilla.javascript.Scriptable) which in turn calls this compileScript mthod 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,
                         org.apache.cocoon.environment.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 org.apache.cocoon.components.flow.Interpreter

Parameters:

funName - a String value

params - a List value

redirector -

Throws:

Exception - if an error occurs

handleContinuation
