public class XMLImportCommand

extends AbstractCommand

This Class implements an import command that deserializes the xml contained in the import stream, using Session.importXML(String, java.io.InputStream, int). It further sets the following properties:

• jcr:mimeType (from ImportContext.getContentType())
• jcr:lastModified (from current time)

Field Summary

static String

XML_CONTENT_TYPE the xml content type

Method Detail

execute

public boolean execute(AbstractContext context)
                throws Exception

Specified by:

execute in class AbstractCommand

Parameters:

context - the (import) context.

Returns:

the return value of the delegated method or false;

Throws:

Exception - in an error occurrs

execute

public boolean execute(ImportContext context)
                throws Exception

Executes this command. It checks if this command can handle the content type and delegates it to importResource(org.apache.jackrabbit.server.io.ImportContext, javax.jcr.Node, java.io.InputStream). If the import is successfull, the input stream of the importcontext is cleared.

Parameters:

context - the import context

Returns:

false

Throws:

Exception - if an error occurrs

importResource

public boolean importResource(ImportContext ctx,
                              Node parentNode,
                              InputStream in)
                       throws Exception

Imports the resource by deseriaizing the xml.

Parameters:

ctx -

parentNode -

in -

Returns:

Throws:

Exception

canHandle

public boolean canHandle(String contentType)

Returns true if the given content type is equal to XML_CONTENT_TYPE.

Parameters:

Returns:

true if equal to XML_CONTENT_TYPE.

getContentNodeType

public String getContentNodeType()

Returns the nodetype for the jcr:content node

Returns:

setContentNodeType

public void setContentNodeType(String contentNodeType)

Sets the nodetype for the jcr:content node.

Parameters:

contentNodeType -

setNodeType

public void setNodeType(String nodeType)
