Class Mp3MetadataSequencer
java.lang.Object
org.modeshape.sequencer.mp3.Mp3MetadataSequencer
- All Implemented Interfaces:
- StreamSequencer
public class Mp3MetadataSequencer
- extends Object
- implements StreamSequencer
A sequencer that processes the binary content of an MP3 audio file, extracts the metadata for the file, and then writes that
audio metadata to the repository.
This sequencer produces data that corresponds to the following structure:
- mp3:metadata node of type
mp3:metadata
- mp3:title - optional string property for the name of the audio file or recording
- mp3:author - optional string property for the author of the recording
- mp3:album - optional string property for the name of the album
- mp3:year - optional integer property for the year the recording as created
- mp3:comment - optional string property specifying a comment

Mp3MetadataSequencer
public Mp3MetadataSequencer()
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
