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 classPOIXMLDocumentPart
- Throws:
java.io.IOException
- a subclass may throw an IOException if the changes can't be committed
-
getCTCalcChain
public org.openxmlformats.schemas.spreadsheetml.x2006.main.CTCalcChain getCTCalcChain()
-
removeItem
public void removeItem(int sheetId, java.lang.String ref)
Remove a formula reference from the calculation chain- Parameters:
sheetId
- the sheet Id of a sheet the formula belongs to.ref
- A1 style reference to the cell containing the formula.
