Rio.getParserFormatForFileName介绍

[英]Tries to match the extension of a file name against the list of RDF formats that can be parsed.
[中]尝试将文件名的扩展名与可解析的RDF格式列表相匹配。

代码示例

代码示例来源：origin: fr.inria.corese/rdf-to-graph

public static Optional<RDFFormat> getRdfFormat(String completeFilename) {
  String[] parts = completeFilename.split(":");
  return Rio.getParserFormatForFileName(parts[0]);
}

代码示例来源：origin: org.openrdf.sesame/sesame-rio-api

@Override
public String probeContentType(Path path)
  throws IOException
{
  Optional<RDFFormat> result = Rio.getParserFormatForFileName(path.getFileName().toString());
  if (result.isPresent()) {
    return result.get().getDefaultMIMEType();
  }
  // Specification says to return null if we could not
  // conclusively determine the file type
  return null;
}

  // System.out.println("**** Parse "+filename);
  File file = new File(filename);

  RDFParser rdfParser = Rio.createParser(Rio.getParserFormatForFileName(file.getName()));
  String streamName = documentURL.toString();
  return parseRDF(inputStream, rdfParser, streamName);
}
