TextExtractor
public TextExtractor()
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
