Class Latin1StringsParser

All Implemented Interfaces:
Serializable, Parser

public class Latin1StringsParser extends AbstractParser
Parser to extract printable Latin1 strings from arbitrary files with pure java without running any external process. Useful for binary or unknown files, for files without a specific parser and for corrupted ones causing a TikaException as a fallback parser. To enable the parsing of unknown or files without a specific parser with AutoDetectParser:

AutoDetectParser parser = new AutoDetectParser(); parser.setFallback(new Latin1StringsParser());

Currently the parser does a best effort to extract Latin1 strings, used by Western European languages, encoded with ISO-8859-1, UTF-8 or UTF-16 charsets mixed within the same file.

The implementation is optimized for fast parsing with only one pass.

    • getMinSize

      public int getMinSize()
      Returns the minimum size of a character sequence to be extracted.
      the minimum size of a character sequence
    • setMinSize

      public void setMinSize(int minSize)
      Sets the minimum size of a character sequence to be extracted.
      minSize - the minimum size of a character sequence
    • getSupportedTypes

      public Set<MediaType> getSupportedTypes(ParseContext arg0)
      Description copied from interface: Parser
      Returns the set of media types supported by this parser when used with the given parse context.
      arg0 - parse context
      immutable set of media types
    • parse

      public void parse(InputStream stream, ContentHandler handler, Metadata metadata, ParseContext context) throws IOException, SAXException
      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
