- Method Detail
  - filter
```
XMLStreamWriter filter(SDDocument doc,
                       XMLStreamWriter w)
                throws XMLStreamException,
                       IOException
```
    Returns a wrapped XMLStreamWriter on top of passed-in XMLStreamWriter. It works like any filtering API for e.g. FilterOutputStream. The method returns a XMLStreamWriter that calls the same methods on original XMLStreamWriter with some modified events. The end result is some infoset is filtered before it reaches the original writer and the infoset writer doesn't have to change any code to incorporate this filter.
    
    Parameters:
    
    doc - gives context for the filter. This should only be used to query read-only information. Calling doc.writeTo() may result in infinite loop.
    
    w - Original XMLStreamWriter
    
    Returns:
    
    Filtering XMLStreamWriter
    
    Throws:
    
    XMLStreamException
    
    IOException
