Package org.apache.tika.parser.strings

Class Latin1StringsParser

java.lang.Object

org.apache.tika.parser.strings.Latin1StringsParser

All Implemented Interfaces:

Serializable, Parser

public class Latin1StringsParser
extends Object
implements Parser

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.

Latin1StringsParser

public Latin1StringsParser()

Method Details

getMinSize

public int getMinSize()

Returns the minimum size of a character sequence to be extracted.

Returns:

the minimum size of a character sequence

setMinSize

public void setMinSize(int minSize)

Sets the minimum size of a character sequence to be extracted.

Parameters:

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.

Specified by:

getSupportedTypes in interface Parser

Parameters:

arg0 - parse context

Returns:

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.

Specified by:

parse in interface Parser

Parameters:

stream - the document stream (input)

handler - handler for the XHTML SAX events (output)

metadata - document metadata (input and output)

context - parse context

Throws:

IOException - if the document stream could not be read

SAXException - if the SAX events could not be processed
