public ExternalLinksTable(PackagePart part)
                   throws IOException

Throws:: IOException
Since:: POI 3.14-Beta1

Method Detail

readFrom

public void readFrom(InputStream is)
              throws IOException

Throws:: IOException

writeTo

public void writeTo(OutputStream out)
             throws IOException

Throws:: IOException

commit
```
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

getCTExternalLink
```
@Internal
@Removal(version="6.0.0")
public org.openxmlformats.schemas.spreadsheetml.x2006.main.CTExternalLink getCTExternalLink()
```
Deprecated.
will be removed because we don't want to expose this (future implementations may not be XMLBeans based)

Returns the underlying xmlbeans object for the external link table. Internal use only. Not currently used internally.

getLinkedFileName
```
public String getLinkedFileName()
```
Returns the last recorded name of the file that this is linked to

setLinkedFileName
```
public void setLinkedFileName(String target)
```
Updates the last recorded name for the file that this links to

getSheetNames
```
public List<String> getSheetNames()
```

getDefinedNames
```
public List<Name> getDefinedNames()
```

cacheData

public void cacheData(String sheetName,
                      long rowR,
                      String cellR,
                      String v)
