Class DWGReadParser

java.lang.Object

org.apache.tika.parser.dwg.AbstractDWGParser

org.apache.tika.parser.dwg.DWGReadParser

All Implemented Interfaces:

Serializable, Parser

public class DWGReadParser
extends AbstractDWGParser

DWGReadParser (CAD Drawing) parser. This extends the original DWGParser if in the parser configuration DwgRead is set. DWG reader can be found here:

https://github.com/LibreDWG/libredwg

DWGRead outputs json which we then loop through extracting the text elements The required configuration is dwgReadExecutable. The other settings which can be overwritten are:

boolean : cleanDwgReadOutput - whether to clean the json output

int : cleanDwgReadOutputBatchSize - clean output batch size to process

long : dwgReadTimeout -timeout in milliseconds before killing the dwgread process

String : cleanDwgReadRegexToReplace - characters to replace in the json

String : cleanDwgReadReplaceWith - * replacement characters dwgReadExecutable

Parameters:

context - parse context

Returns:

immutable set of media types

parse

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.

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

TikaException - if the document could not be parsed
