    Description copied from class: DataSource
    
    Provides a new InputStream for this data source. This method should be implemented by subclasses to provide a new InputStream giving the raw content of the source each time it is called. The general contract of this method is that each time it is called it will return a stream with the same content.
    
    Specified by:
    
    getRawInputStream in class DataSource
    
    Returns:
    
    an InputStream containing the data of this source
    
    Throws:
    
    java.io.IOException
  - getURL
```
public java.net.URL getURL()
```
    Returns the URL on which this URLDataSource is based.
    
    Overrides:
    
    getURL in class DataSource
    
    Returns:
