- 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.
    If your session tool depends on having a User object, you should look at implementing the RunDataApplicationTool interface instead.
    Parameters:
    
    data - initialization data
  - refresh
```
void refresh()
```
    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
