- Method Detail
  - init
```
void init(Object data)
```
    Initialize the application tool. The data parameter holds a different type depending on how the tool is being instantiated:
    
    For global tools data will be null
    
    For request tools data will be of type RunData
    
    For session and authorized tools data will be of type User
    
    It is possible that session scope tools will be initialized with a null User object. This happens when the first request on a session happens to the be login action. The next request on the session will cause the session tool to be refreshed if tools.per.request.refresh is set to true in TurbineResources.properties. You will then be able to get a User object from the instance of RunData.
    Parameters:
    
    data - initialization data
  - refresh
```
void refresh(RunData data)
```
    Refresh the application tool. This is necessary for development work where you probably want the tool to refresh itself if it is using configuration information that is typically cached after initialization
    
    Parameters:
    
    data - The current RunData Object
