POIXMLDocumentPart
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(); }(将内容保存在底层包部分中。默认实现是空的,这意味着包部分保持不变。子类应覆盖并添加逻辑以将“模型”编组到 Ooxml4J。例如,保存通用 XML 条目的代码可能如下所示: protected void commit() throws IOException { PackagePart part = getPackagePart();输出流输出 = part.getOutputStream(); XmlObject bean = getXmlBean(); //保存内存变化的“模型” bean.save(out, DEFAULT_XML_OPTIONS); out.close(); })

java.io.IOException
- a subclass may throw an IOException if the changes can't be committed
(java.io.IOException - 如果无法提交更改,子类可能会抛出 IOException)
@Beta public AreaReference getPivotArea(Workbook wb) throws java.lang.IllegalArgumentException
java.lang.IllegalArgumentException
- if the ref attribute is not contiguous or the name attribute is not found.
(java.lang.IllegalArgumentException - 如果 ref 属性不连续或未找到 name 属性。)
