Method Detail

run

public void run(SlingHttpServletRequest request,
                PostResponse response,
                SlingPostProcessor[] processors)

Deprecated.

Prepares and finalizes the actual operation. Preparation encompasses getting the absolute path of the item to operate on by calling the getItemPath(SlingHttpServletRequest) method and setting the location and parent location on the response. After the operation has been done in the doRun(SlingHttpServletRequest, PostResponse, List) method the session is saved if there are unsaved modifications. In case of errorrs, the unsaved changes in the session are rolled back.

Specified by:

run in interface PostOperation

Parameters:

request - the request to operate on

response - The PostResponse to record execution progress.

processors - The array of processors

doRun

protected abstract void doRun(SlingHttpServletRequest request,
                              PostResponse response,
                              List<Modification> changes)
                       throws javax.jcr.RepositoryException

Deprecated.

Actually performs the desired operation filling progress into the changes list and preparing and further information in the response.

The response comes prepared with the path, location and parent location set. Other properties are expected to be set by this implementation.

Parameters:

request - The SlingHttpServletRequest providing the input, mostly in terms of request parameters, to the operation.

response - The PostResponse to fill with response information

changes - A container to add Modification instances representing the operations done.

Throws:

javax.jcr.RepositoryException - Maybe thrown if any error occurrs while accessing the repository.

getVersioningConfiguration

protected VersioningConfiguration getVersioningConfiguration(SlingHttpServletRequest request)

Deprecated.

Get the versioning configuration.

Parameters:

request - The http request

Returns:

The versioning configuration

isSkipCheckin

protected boolean isSkipCheckin(SlingHttpServletRequest request)

Deprecated.

Check if checkin should be skipped

Parameters:

request - The http request

Returns:

true if checkin should be skipped

isSkipSessionHandling

protected boolean isSkipSessionHandling(SlingHttpServletRequest request)

Deprecated.

Check whether changes should be written back

Parameters:

request - The http request

Returns:

true If session handling should be skipped

isSessionSaveRequired

protected boolean isSessionSaveRequired(javax.jcr.Session session,
                                        SlingHttpServletRequest request)
                                 throws javax.jcr.RepositoryException

Deprecated.

Check whether commit to the resource resolver should be called.

Parameters:

session - The JCR session

request - The http request

Returns:

true if a save is required.

Throws:

javax.jcr.RepositoryException

removeAndValidateWorkspace

protected String removeAndValidateWorkspace(String path,
                                            javax.jcr.Session session)
                                     throws javax.jcr.RepositoryException

Deprecated.

Remove the workspace name, if any, from the start of the path and validate that the session's workspace name matches the path workspace name.

Parameters:

path - The path

session - The JCR session

Returns:

The path without the workspace

Throws:

javax.jcr.RepositoryException

getItemPath

protected String getItemPath(SlingHttpServletRequest request)

Deprecated.

Returns the path of the resource of the request as the item path.

This method may be overwritten by extension if the operation has different requirements on path processing.

Parameters:

request - The http request

Returns:

The item path

getApplyToResources

protected Iterator<Resource> getApplyToResources(SlingHttpServletRequest request)

Deprecated.

Returns an iterator on Resource instances addressed in the SlingPostConstants.RP_APPLY_TO request parameter. If the request parameter is not set, null is returned. If the parameter is set with valid resources an empty iterator is returned. Any resources addressed in the SlingPostConstants.RP_APPLY_TO parameter is ignored.

Parameters:

Returns:

The iterator of resources listed in the parameter or null if the parameter is not set in the request.
