public class WebDAVTransformer
extends AbstractSAXTransformer
implements Disposable, CacheableProcessingComponent

A general purpose, low level webdav transformer. Sends http requests defined in xml directly to the server and returns the response to the processing stream. For a more high level approach, use WebDAVSource (GET/PUT/PROPPATCH) and DASLTransformer (SEARCH).

Method Detail

setup

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

Description copied from interface: SitemapModelComponent

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 AbstractSAXTransformer

Throws:

ProcessingException

SAXException

IOException

recycle

public void recycle()

Description copied from class: AbstractXMLProducer

Recycle the producer by removing references, and resetting handlers to null (empty) implementations.

Specified by:

recycle in interface Recyclable

Overrides:

recycle in class AbstractSAXTransformer

dispose

public void dispose()

Specified by:

dispose in interface Disposable

Overrides:

dispose in class AbstractSAXTransformer

startElement

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

Description copied from class: AbstractSAXTransformer

Process the SAX event. The namespace of the event is checked. If it is the defined namespace for this transformer, the AbstractSAXTransformer.startTransformingElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes) hook is called.

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class AbstractSAXTransformer

Parameters:

uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.

name - The local name (without prefix), or the empty string if Namespace processing is not being performed.

raw - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.

atts - The attributes attached to the element. If there are no attributes, it shall be an empty Attributes object.

Throws:

SAXException

See Also:

ContentHandler.startElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes)

endElement

public void endElement(String uri,
                       String name,
                       String raw)
                throws SAXException

Description copied from class: AbstractSAXTransformer

Process the SAX event. The namespace of the event is checked. If it is the defined namespace for this transformer, the AbstractSAXTransformer.endTransformingElement(java.lang.String, java.lang.String, java.lang.String) hook is called.

Specified by:

endElement in interface ContentHandler

Overrides:

endElement in class AbstractSAXTransformer

Parameters:

uri - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.

name - The local name (without prefix), or the empty string if Namespace processing is not being performed.

raw - The raw XML 1.0 name (with prefix), or the empty string if raw names are not available.

Throws:

SAXException

See Also:

ContentHandler.endElement(java.lang.String, java.lang.String, java.lang.String)

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.
