public interface StreamSequencer
The interface for a DNA sequencer that processes a property as a stream to extract information from the content and store in the repository.
Implementations must provide a no-argument constructor.

void sequence(InputStream stream, SequencerOutput output, StreamSequencerContext context)
JBoss DNA's SequencingService determines the sequencers that should be executed by monitoring the changes to one or more workspaces that it is monitoring. Changes in those workspaces are aggregated and used to determine which sequencers should be called. If the sequencer implements this interface, then this method is called with the property that is to be sequenced along with the interface used to register the output. The framework takes care of all the rest.
stream
- the stream with the data to be sequenced; never null
output
- the output from the sequencing operation; never null
context
- the context for the sequencing operation; never null
