Class TextAndCSVParser

All Implemented Interfaces:
Serializable, Parser

public class TextAndCSVParser extends AbstractEncodingDetectorParser
Unless the TikaCoreProperties.CONTENT_TYPE_USER_OVERRIDE is set, this parser tries to assess whether the file is a text file, csv or tsv. If the detector detects regularity in column numbers and/or encapsulated cells, this parser will apply the CSVParser; otherwise, it will treat the contents as text.

If there is a csv parse exception during detection, the parser sets the HttpHeaders.CONTENT_TYPE to MediaType.TEXT_PLAIN and treats the file as MediaType.TEXT_PLAIN.

If there is a csv parse exception during the parse, the parser writes what's left of the stream as if it were text and then throws an exception. As of this writing, the content that was buffered by the underlying CSVParser is lost.

      public void parse(InputStream stream, ContentHandler handler, Metadata metadata, ParseContext context) throws IOException, SAXException, TikaException
      Description copied from interface: Parser
      Parses a document stream into a sequence of XHTML SAX events. Fills in related document metadata in the given metadata object.

      The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

      Information about the parsing context can be passed in the context parameter. See the parser implementations for the kinds of context information they expect.

      stream - the document stream (input)
      handler - handler for the XHTML SAX events (output)
      metadata - document metadata (input and output)
      context - parse context
      IOException - if the document stream could not be read
      SAXException - if the SAX events could not be processed
      TikaException - if the document could not be parsed
