Interface IDocumentReader

@PublicApi public interface IDocumentReader
The IDocumentReader interface gives the functionality to read the Chemical Structures from a given document.

  • Method Details

    • getAllStructures

      List<MoleculeMap> getAllStructures() throws Exception
      Reads all the molecules from the given document
      Returns:
      MoleculeMap array with the molecules and their locations
      Throws:
      Exception

    • isDocumentJCO

      boolean isDocumentJCO()
      Determines if the document contains JCO structure.
      Returns:
      True if the document contains JCO structure.

    • isObjectJCO

      MoleculeMap isObjectJCO(Object range)
      Determines if the given POI object can be handled as a JCO object with molecule content.

      Example how to use the isObjectJCO from PowerPoint: 

       XMLSlideShow pptx = new XMLSlideShow(inputStream);
 XSLFShape groupShape = pptx.getSlides().get(0).getShapes().get(0);
 XSLFShape pictureShape = null;
 List innerShapes = ((XSLFGroupShape) groupShape).getShapes();
 for (XSLFShape innerShape : innerShapes) {
     if (innerShape.getClass().getName().equals("org.apache.poi.xslf.usermodel.XSLFPictureShape")) {
         pictureShape = innerShape;
        }
 }
 inputStream.close();
 IDocumentReader reader = DocumentHandlerFactory.CreateReader(inputStream);
 -- Check group shape
 MoleculeMap map = reader.isObjectJCO(groupShape);
 -- or Check picture shape
 MoleculeMap map = reader.isObjectJCO(pictureShape);

      Example how to use the isObjectJCO from Word: 

       XWPFDocument doc = new XWPFDocument(inputStream);
 XWPFParagraph paragraph = doc.getTables().get(0).getRow(0).getTableCells().get(0).getParagraphs().get(0);
 XWPFRun run = paragraph.getRuns().get(0);
 inputStream.close();
 IDocumentReader reader = DocumentHandlerFactory.CreateReader(inputStream);
 -- Check the paragraph
 MoleculeMap mapPicture = reader.isObjectJCO(paragraph);
 -- Or check the run
 MoleculeMap mapPicture = reader.isObjectJCO(run);
 inputStream.close();
 reader.close();
      Parameters:
      range - - The POI object (i.e.: groupShape, pictureShape, paragraph, run)
      Returns:
      If the passed parameter is a JCO object it returns the MoleculeMap from it otherwise returns an empty MoleculeMap object.

    • close

      void close() throws IOException
      Closes the office document stream.
      Throws:
      IOException

    • getExceptions

      BatchProcessingException getExceptions()
      Gives back all exceptions occurred while processing the document.
      Returns:
      Returns with a throwable IOException that collects inner exceptions occurred in the batch processing.
