Examples of com.mongodb.gridfs.GridFSInputFile

com.mongodb.gridfs.GridFSInputFile
This class represents a GridFS file to be written to the database Operations include: - writing data obtained from an InputStream - getting an OutputStream to stream the data out @author Eliot Horowitz and Guy K. Kloss


      MongoRepository mongoRepository = (MongoRepository) repository;


      GridFS gridFS = mongoRepository.getGridFS();


      GridFSInputFile file = gridFS.createFile(new File(
          "test-files/sample.txt"));

      file.save();


      List<GridFSDBFile> files = gridFS.find((DBObject) JSON
          .parse("{ _id : 'sample.txt' }"));
