The SAXSource
class allows the setting of an XMLReader
to be used for pulling parse events, and an InputSource
that may be used to specify the SAX source.
The SAXResult
class allows the setting of a ContentHandler
to be the receiver of SAX2 events from the transformation.
The SAXTransformerFactory
extends TransformerFactory
to provide factory methods for creating TemplatesHandler
, TransformerHandler
, and XMLReader
instances.
To obtain a SAXTransformerFactory
, the caller must cast the TransformerFactory
instance returned from TransformerFactory.newInstance()
.
The TransformerHandler
interface allows a transformation to be created from SAX2 parse events, which is a "push" model rather than the "pull" model that normally occurs for a transformation. Normal parse events are received through the ContentHandler
interface, lexical events such as startCDATA and endCDATA are received through the LexicalHandler
interface, and events that signal the start or end of disabling output escaping are received via ContentHandler.processingInstruction(java.lang.String, java.lang.String)
, with the target parameter being Result.PI_DISABLE_OUTPUT_ESCAPING
and Result.PI_ENABLE_OUTPUT_ESCAPING
. If parameters, output properties, or other features need to be set on the Transformer handler, a Transformer
reference will need to be obtained from TransformerHandler.getTransformer()
, and the methods invoked from that reference.
The TemplatesHandler
interface allows the creation of Templates
objects from SAX2 parse events. Once the ContentHandler
events are complete, the Templates object may be obtained from TemplatesHandler.getTemplates()
. Note that TemplatesHandler.setSystemId(java.lang.String)
should normally be called in order to establish a base system ID from which relative URLs may be resolved.
The SAXTransformerFactory.newXMLFilter(javax.xml.transform.Source)
method allows the creation of a XMLFilter
, which encapsulates the SAX2 notion of a "pull" transformation. The resulting XMLFilters
can be chained together so that a series of transformations can happen with one's output becoming another's input.
Class | Description |
---|---|
SAXResult | Acts as an holder for a transformation Result. |
SAXSource | Acts as an holder for SAX-style Source. |
SAXTransformerFactory | This class extends TransformerFactory to provide SAX-specific factory methods. |
TemplatesHandler | A SAX ContentHandler that may be used to process SAX parse events (parsing transformation instructions) into a Templates object. |
TransformerHandler | A TransformerHandler listens for SAX ContentHandler parse events and transforms them to a Result. |
