public XSLTProcessor()

Method Detail

init

public void init(Director director)

Description copied from interface: Actor

Initialize the actor by indicating their director.

Specified by:

init in interface Actor

process

public org.w3c.dom.Document process(org.w3c.dom.Document document,
                                    java.util.Dictionary parameters)
                             throws java.lang.Exception

Description copied from interface: Processor

Process the DOM tree. The returned tree is allowed to be either a copy or the modified input tree.

Specified by:

process in interface Processor

hasChanged

public boolean hasChanged(java.lang.Object context)

Description copied from interface: Changeable

Returns false if the requested resource hasn't changed, true otherwise. This method is called by the cache system to ensure the validity of the cached response. It is the producer responsibility to provide the fastest possible implementation of this method or, whether this is not possible and the costs of the change evaluation is comparable to the production costs, to return true directly with no further delay, thus reducing the evaluation overhead to a minimum. This method is guaranteed to be called after at least a single call to any production methods getStream or getDocument. The context is the trigger of the changeable point and may differ between implementations.

Specified by:

hasChanged in interface Changeable

isCacheable

public boolean isCacheable(javax.servlet.http.HttpServletRequest request)

Description copied from interface: Cacheable

Returns whether this request is suitable for cacheing.

Specified by:

isCacheable in interface Cacheable

getStatus

public java.lang.String getStatus()

Description copied from interface: Status

Returns information about the status of the implementing class. Note: this is use instead of the usual toString() method because some of these methods are declared final in some classes in JDK 1.1.

Specified by:

getStatus in interface Status
