XSSFPivotCacheRecords

@Beta
protected XSSFPivotCacheRecords(PackagePart part)
                               throws java.io.IOException

Creates an XSSFPivotCacheRecords representing the given package part and relationship. Should only be called when reading in an existing file. (创建一个表示给定包部分和关系的 XSSFPivotCacheRecords。仅应在读取现有文件时调用。)

Parameters:

part - - The package part that holds xml data representing this pivot cache records. (part - 包含表示此数据透视缓存记录的 xml 数据的包部分。)

Throws:

java.io.IOException (java.io.IOException)

Since:

POI 3.14-Beta1

commit

@Beta
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();
 }
 

(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(); })

Overrides:

commit in class POIXMLDocumentPart

Throws:

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)
