Constructor Detail

### TextExtractor

    public TextExtractor()

Method Detail

### supportsMimeType

    public abstract boolean supportsMimeType(String mimeType)

  Determine if this extractor is capable of processing content with the supplied MIME type.

  Parameters:
    `mimeType` - the MIME type; never null
  Returns:
    true if this extractor can process content with the supplied MIME type, or false otherwise.

### extractFrom

    public abstract void extractFrom(InputStream stream,
                                     TextExtractorOutput output,
                                     TextExtractor.Context context)
                              throws IOException

  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.

  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`
  Throws:
    `IOException` - if there is a problem reading the stream

### setLogger

    protected final void setLogger(Logger logger)

### getLogger

    protected final Logger getLogger()
