Constructor Detail

### MSOfficeMetadataSequencer

    public MSOfficeMetadataSequencer()

Method Detail

### sequence

    public void sequence(InputStream stream,
                         SequencerOutput output,
                         StreamSequencerContext context)

  Sequence the data found in the supplied stream, placing the output information into the supplied map.

  ModeShape'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.

  Specified by:
    `sequence` in interface `StreamSequencer`
  Parameters:
    `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`

### recordMetadata

    protected void recordMetadata(SequencerOutput output,
                                  StreamSequencerContext context,
                                  Path metadataNode,
                                  MSOfficeMetadata metadata)
