Class OfbizBshBsfEngine

java.lang.Object
  BSFEngineImpl
      org.ofbiz.base.util.OfbizBshBsfEngine

public class OfbizBshBsfEngine
extends BSFEngineImpl

This is the BeanShell adapter for IBM's Bean Scripting Famework. It is an implementation of the BSFEngine class, allowing BSF aware applications to use BeanShell as a scripting language.

I believe this implementation is complete (with some hesitation about the the usefullness of the compileXXX() style methods - provided by the base utility class).

Method Detail

initialize

public void initialize(BSFManager mgr,
                       java.lang.String lang,
                       java.util.Vector declaredBeans)
                throws BSFException

Throws:

BSFException

setDebug

public void setDebug(boolean debug)

call

public java.lang.Object call(java.lang.Object object,
                             java.lang.String name,
                             java.lang.Object[] args)
                      throws BSFException

Invoke method name on the specified bsh scripted object. The object may be null to indicate the global namespace of the interpreter.

Parameters:

object - may be null for the global namespace.

Throws:

BSFException

apply

public java.lang.Object apply(java.lang.String source,
                              int lineNo,
                              int columnNo,
                              java.lang.Object funcBody,
