XSSFPivotCacheDefinition

@Beta
protected XSSFPivotCacheDefinition(PackagePart part)
                            throws IOException

Creates an XSSFPivotCacheDefintion representing the given package part and relationship. Should only be called when reading in an existing file.

Parameters:

part - - The package part that holds xml data representing this pivot cache definition.

Throws:

IOException

Since:

POI 3.14-Beta1

Method Detail

readFrom

@Beta
public void readFrom(InputStream is)
              throws IOException

Throws:

IOException

getCTPivotCacheDefinition

@Beta
@Internal
public org.openxmlformats.schemas.spreadsheetml.x2006.main.CTPivotCacheDefinition getCTPivotCacheDefinition()

commit

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

Overrides:

commit in class POIXMLDocumentPart

Throws:

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

getPivotArea

@Beta
public AreaReference getPivotArea(Workbook wb)
                           throws IllegalArgumentException

Find the 2D base data area for the pivot table, either from its direct reference or named table/range.

Returns:

AreaReference representing the current area defined by the pivot table

Throws:

IllegalArgumentException - if the ref attribute is not contiguous or the name attribute is not found.

createCacheFields

@Beta
protected void createCacheFields(Sheet sheet)

Generates a cache field for each column in the reference area for the pivot table.

Parameters:

sheet - The sheet where the data i collected from
