Constructor Detail

EncodeURLTransformer

public EncodeURLTransformer()

Method Detail

checkForEncoding

protected void checkForEncoding(Request request)

check if encoding of URLs is neccessary. This is true if session object exists, and session-id was provided from URL, or session is new. The result is stored in some instance variables

setup

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

Setup the transformer.

Setup include, and exclude patterns from the parameters

Specified by:

setup in interface SitemapModelComponent

Parameters:

resolver - source resolver

objectModel - sitemap objects

parameters - request parameters

Throws:

ProcessingException

SAXException

IOException

configure

public void configure(Configuration configuration)
               throws ConfigurationException

BEGIN SitemapComponent methods

Specified by:

configure in interface Configurable

Parameters:

configuration - Description of Parameter

Throws:

ConfigurationException - Description of Exception

recycle

public void recycle()

Recycle resources of this transformer

Specified by:

recycle in interface Recyclable

Overrides:

recycle in class AbstractXMLProducer

getKey

public Serializable getKey()

Generate the unique key. This key must be unique inside the space of this component.

Specified by:

getKey in interface CacheableProcessingComponent

Returns:

The generated key hashes the src

getValidity

public SourceValidity getValidity()

Generate the validity object.

Specified by:

getValidity in interface CacheableProcessingComponent

Returns:

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

startElement

public void startElement(String uri,
                         String name,
                         String raw,
                         Attributes attributes)
                  throws SAXException

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class AbstractXMLPipe

Parameters:

uri - of the element

name - of the element

raw - name of the element

attributes - list

Throws:

SAXException - Description of Exception
