Method Detail

getAllStructures

java.util.List<MoleculeMap> getAllStructures()
                                      throws java.lang.Exception

Reads all the molecules from the given document

Returns:

MoleculeMap array with the molecules and their locations

Throws:

java.lang.Exception

isDocumentJCO

boolean isDocumentJCO()

Determines if the document contains JCO structure.

Returns:

True if the document contains JCO structure.

isObjectJCO

MoleculeMap isObjectJCO(java.lang.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 java.io.IOException

Closes the office document stream.

Throws:

java.io.IOException

getExceptions

chemaxon.formats.documents.jchemoffice.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.
