org.apache.jackrabbit.server.io.ZipHandler
ZipHandler
imports and extracts Zip files and exported nodes
(an their subnodes) to a Zip file. Please not that for the export the selected
export root must have the property ZIP_MIMETYPE
defined with its
content. Furthermore the content must not represent a zip-file that has
been imported to a binary property
, which is properly
handled by the DefaultHandler
.
Field Summary | |
static String |
ZIP_MIMETYPE
the zip mimetype |
Constructor Summary | |
ZipHandler(IOManager ioManager)
Creates a new ZipHandler with default nodetype definitions:Nodetype for Collection: nt:unstructured
Nodetype for Non-Collection: nt:file
Nodetype for Non-Collection content: nt:unstructured
|
|
ZipHandler(IOManager ioManager,
String collectionNodetype,
String defaultNodetype,
String contentNodetype)
Creates a new ZipHandler |
Method Summary | |
boolean |
canExport(ExportContext context,
boolean isCollection)
Returns true if the export root is a node and if it contains a child node with name jcr:content in case this
export is not intended for a collection. |
boolean |
canImport(ImportContext context,
boolean isCollection)
Returns true, if this handler can run a successful import based on the specified context. |
protected void |
exportData(ExportContext context,
boolean isCollection,
Node contentNode)
Checks if the given content node contains a jcr:data property and spools its value to the output stream fo the export context. Please note, that subclasses that define a different structure of the content node should create their own exportData method. |
protected boolean |
importData(ImportContext context,
boolean isCollection,
Node contentNode)
Imports the data present on the import context to the specified content node. |
void |
setIntermediateSave(boolean intermediateSave)
If set to true the import root will be saved
after every imported zip entry. |

true
the import root will be saved
after every imported zip entry. Note however, that this removes the possibility
to revert all modifications if the import cannot be completed successfully.
By default the intermediate save is disabled.
