```
public interface ScriptExtension

    Get all the scripting objects the extension exports wrapped as ContextItem objects. This method will be called each time a script is run from a ScriptExtensionPoint that defines a particular extension, so it should be fast.
    
    Returns:
    
    A List of ContextItem objects.
  - initialize
```
void initialize(ScriptInterface si,
                ScriptContextDAO dao)
         throws ScriptException,
                java.lang.IllegalArgumentException
```
    Initialize the ScriptExtension by providing a reference to the ScriptInterface this extension should use to set its state. Only a ScriptEvaluator should call this method.
    
    Parameters:
    
    si - This ScriptInterface must be downcastable to the correct specific type for the given extension.
    
    dao - The Data Access Object to use to lookup and place items into the scripting environment.
    
    Throws:
    
    ScriptException - If an error occurs while initializing the extension.
    
    java.lang.IllegalArgumentException - If si is not the correct type for the given extension.
