- Method Detail
  - getStateChange
```
ProcessingStateChange getStateChange(Invocation invocation,
                                     XMLStreamWriter writer)
```
    Based on the current invocation decides whether a processing state change is required and returns the result of this decision.
    
    Parameters:
    
    invocation - current invocation executed on the XML stream writer
    
    writer - mirror writer that records all calls (even the ones filtered out) and thus represents the "unfiltered" status of the XML stream. The parameter may be used to query the status. Implementations of the FilteringStateMachine SHOULD NOT call any methods that may result in a modification of the XML stream represented by this writer parameter.
    
    Returns:
    
    processing state change as required.
