Method Detail

setup

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

Set the request parameters. Must be called before the generate method.

Specified by:

setup in interface SitemapModelComponent

Overrides:

setup in class AbstractGenerator

Parameters:

resolver - the SourceResolver object

objectModel - a Map containing model object

src - the source URI (ignored)

par - configuration parameters

Throws:

ProcessingException

SAXException

IOException

generate

public void generate()
              throws SAXException,
                     ProcessingException

Generate XML data.

Specified by:

generate in interface Generator

Throws:

SAXException - if an error occurs while outputting the document

ProcessingException

addContent

protected void addContent(Calendar date,
                          Locale locale)
                   throws SAXException

Parameters:

date - The date corresponding to the current element.

locale - The current locale.

Throws:

SAXException - if an error occurs while outputting the document

getKey

public Serializable getKey()

Description copied from interface: CacheableProcessingComponent

Generate the unique key. This key must be unique inside the space of this component. This method must be invoked before the getValidity() method.

Specified by:

getKey in interface CacheableProcessingComponent

Returns:

The generated key or null if the component is currently not cacheable.

getValidity

public SourceValidity getValidity()

Description copied from interface: CacheableProcessingComponent

Generate the validity object. Before this method can be invoked the getKey() method must be invoked.

Specified by:

getValidity in interface CacheableProcessingComponent

Returns:

The generated validity object or null if the component is currently not cacheable.

recycle

public void recycle()

Recycle resources

Specified by:

recycle in interface Recyclable

Overrides:

recycle in class AbstractGenerator
