commit
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
