public class TraversableSourceDescriptionGenerator
extends TraversableGenerator

This Generator augments the output of the TraversableGenerator.

It adds:

• version information if the Source implements VersionableSource.
• locking information if the Source implements Lockablesource.
• permission information if the Source implements RestrictableSource.
• and describes its SourceProperties if the Source implements InspectableSource.

Sitemap parameters that can be specified to control processing are:

• version (true) whether to generate versioning information.
• locking (true) whether to generate locking information.
• permission (true) whether to generate permission information.
• properties (true) whether to generate source property information.

Method Detail

setup

public void setup(SourceResolver resolver,
                  Map objectModel,
                  String location,
                  Parameters parameters)
           throws ProcessingException,
                  SAXException,
                  IOException

Set the SourceResolver, objectModel Map, the source and sitemap Parameters used to process the request.

Specified by:

setup in interface SitemapModelComponent

Overrides:

setup in class TraversableGenerator

Parameters:

resolver - Source Resolver

objectModel - Object model.

location - Location of the source.

parameters - Parameters for the generator.

Throws:

ProcessingException

SAXException

IOException

addContent

protected final void addContent(TraversableSource source)
                         throws SAXException,
                                ProcessingException

Augments source nodes with additional information.

Overrides:

addContent in class TraversableGenerator

Parameters:

source - the Source to describe.

Throws:

SAXException

ProcessingException

setNodeAttributes

protected void setNodeAttributes(TraversableSource source)
                          throws SAXException,
                                 ProcessingException

Augments source node elements with additional attributes describing the Source. The additional attributes are a mimeType attribute, and iff the Source is an instance of VersionableSource and the generator is configured to output versioning information two attributes: revision and branch.

Overrides:

setNodeAttributes in class TraversableGenerator

Parameters:

source - the Source to describe.

Throws:

SAXException

ProcessingException

pushSourceLocks

public void pushSourceLocks(LockableSource source)
                     throws SAXException,
                            SourceException

Push a XML description about all locks of a source.

Parameters:

source - the Source to describe.

Throws:

SAXException

SourceException
