commit

protected void commit()
               throws java.io.IOException

Description copied from class: POIXMLDocumentPart

Save the content in the underlying package part. Default implementation is empty meaning that the package part is left unmodified. Sub-classes should override and add logic to marshal the "model" into Ooxml4J. For example, the code saving a generic XML entry may look as follows:

 protected void commit() throws IOException {
   PackagePart part = getPackagePart();
   OutputStream out = part.getOutputStream();
   XmlObject bean = getXmlBean(); //the "model" which holds changes in memory
   bean.save(out, DEFAULT_XML_OPTIONS);
   out.close();
 }
 

Overrides:

commit in class POIXMLDocumentPart

Throws:

java.io.IOException - a subclass may throw an IOException if the changes can't be committed
