public static void registerSelectedAccumulators(WatchManager watchManager,
                                                java.util.Set<? extends Accumulator> accumulators)
                                         throws XPathException
```
    Register all the rules for all the accumulators with a WatchManager handling events for a streaming pass over a source document
    
    Parameters:
    
    watchManager - the WatchManager with which the rules are to be registered
    
    Throws:
    
    XPathException - if an error occurs
  - getStreamingAccumulatorValue
```
public Sequence getStreamingAccumulatorValue(NodeInfo node,
                                             Accumulator accumulator,
                                             AccumulatorFn.Phase phase)
                                      throws XPathException
```
    Get the run-time value of a streamed accumulator
    
    Overrides:
    
    getStreamingAccumulatorValue in class AccumulatorRegistry
    
    Parameters:
    
    node - the context node
    
    accumulator - the accumulator whose value is required
    
    phase - pre-descent or post-descent
    
    Returns:
    
    the value of the accumulator, or null if the context node is not streamed
    
    Throws:
    
    XPathException - if a dynamic error occurs
