Class ZipHandler

java.lang.Object
  org.apache.jackrabbit.server.io.DefaultHandler
      org.apache.jackrabbit.server.io.ZipHandler

All Implemented Interfaces:

IOHandler, PropertyHandler

public class ZipHandler
extends DefaultHandler

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()
Creates a new ZipHandler with default nodetype definitions and without setting the IOManager.

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, javax.jcr.Node contentNode) Checks if the given content node contains a jcr:data property and spools its value to the output stream of the export context.
protected boolean	importData(ImportContext context, boolean isCollection, javax.jcr.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.

Constructor Detail

ZipHandler

public ZipHandler()

Creates a new ZipHandler with default nodetype definitions and without setting the IOManager.

See Also:

IOHandler.setIOManager(IOManager)

ZipHandler

public 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

Parameters:

ioManager -

Throws:

IllegalArgumentException - if the specified IOManager is null

ZipHandler

public ZipHandler(IOManager ioManager,
                  String collectionNodetype,
                  String defaultNodetype,
                  String contentNodetype)

Creates a new ZipHandler

Parameters:

ioManager -

collectionNodetype -

defaultNodetype -

contentNodetype -

Throws:

IllegalArgumentException - if the specified IOManager is null

Method Detail

setIntermediateSave

public void setIntermediateSave(boolean intermediateSave)

If set to 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.

Parameters:

intermediateSave -

canImport

public boolean canImport(ImportContext context,
                         boolean isCollection)

Description copied from interface: IOHandler

Returns true, if this handler can run a successful import based on the specified context.

Specified by:

canImport in interface IOHandler

Overrides:

canImport in class DefaultHandler

Returns:

See Also:

IOHandler.canImport(ImportContext, boolean)

importData

protected boolean importData(ImportContext context,
                             boolean isCollection,
                             javax.jcr.Node contentNode)
                      throws IOException,
                             javax.jcr.RepositoryException

Description copied from class: DefaultHandler

Imports the data present on the import context to the specified content node.

Overrides:

importData in class DefaultHandler

Returns:

Throws:

IOException

javax.jcr.RepositoryException

See Also:

DefaultHandler.importData(ImportContext, boolean, Node)

canExport

public boolean canExport(ExportContext context,
                         boolean isCollection)

Description copied from class: DefaultHandler

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.

Specified by:

canExport in interface IOHandler

Overrides:

canExport in class DefaultHandler

Returns:

true if the export root is a node. If the specified boolean parameter is false (not a collection export) the given export root must contain a child node with name jcr:content.

See Also:

IOHandler.canExport(ExportContext, boolean)

exportData

protected void exportData(ExportContext context,
                          boolean isCollection,
                          javax.jcr.Node contentNode)
                   throws IOException,
                          javax.jcr.RepositoryException

Description copied from class: DefaultHandler

Checks if the given content node contains a jcr:data property and spools its value to the output stream of the export context.
Please note, that subclasses that define a different structure of the content node should create their own exportData method.

Overrides:

exportData in class DefaultHandler

Parameters:

context - export context

isCollection - true if collection

contentNode - the content node

Throws:

IOException - if an I/O error occurs

javax.jcr.RepositoryException
