This class implements an identity transformer for
SAXTransformerFactory.newTransformerHandler()
and TransformerFactory.newTransformer()
. It
simply feeds SAX events directly to a serializer ContentHandler, if the
result is a stream. If the result is a DOM, it will send the events to
DOMBuilder
. If the result is another
content handler, it will simply pass the events on.

Method Detail |
public void setResult(Result result) throws java.lang.IllegalArgumentException
result
- A Result instance, should not be null.public void setSystemId(java.lang.String systemID)
systemID
- Base URI for the source tree.public java.lang.String getSystemId()
setSystemId(java.lang.String)
.public Transformer getTransformer()
public void reset()
public void transform(Source source, Result outputTarget) throws TransformerException
source
- The input for the source tree.outputTarget
- The output target.public void setParameter(java.lang.String name, java.lang.Object value)
Pass a qualified name as a two-part string, the namespace URI enclosed in curly braces ({}), followed by the local name. If the name has a null URL, the String only contain the local name. An application can safely check for a non-null URI by testing to see if the first character of the name is a '{' character.
For example, if a URI and local name were obtained from an element defined with <xyz:foo xmlns:xyz="http://xyz.foo.com/yada/baz.html"/>, then the qualified name would be "{http://xyz.foo.com/yada/baz.html}foo". Note that no prefix is used.
name
- The name of the parameter, which may begin with a namespace URI
in curly braces ({}).value
- The value object. This can be any valid Java object. It is
up to the processor to provide the proper object coersion or to simply
pass the object on for use in an extension.public java.lang.Object getParameter(java.lang.String name)
This method does not return a default parameter value, which cannot be determined until the node context is evaluated during the transformation process.
name
- Name of the parameter.public void clearParameters()
public void setURIResolver(URIResolver resolver)
If the resolver argument is null, the URIResolver value will be cleared, and the default behavior will be used.
resolver
- An object that implements the URIResolver interface,
or null.public URIResolver getURIResolver()
public void setOutputProperties(java.util.Properties oformat) throws java.lang.IllegalArgumentException
If argument to this function is null, any properties previously set are removed, and the value will revert to the value defined in the templates object.
Pass a qualified property key name as a two-part string, the namespace URI enclosed in curly braces ({}), followed by the local name. If the name has a null URL, the String only contain the local name. An application can safely check for a non-null URI by testing to see if the first character of the name is a '{' character.
For example, if a URI and local name were obtained from an element defined with <xyz:foo xmlns:xyz="http://xyz.foo.com/yada/baz.html"/>, then the qualified name would be "{http://xyz.foo.com/yada/baz.html}foo". Note that no prefix is used.
oformat
- A set of output properties that will be
used to override any of the same properties in affect
for the transformation.OutputKeys
,
Properties
public java.util.Properties getOutputProperties()
The properties returned should contain properties set by the user,
and properties set by the stylesheet, and these properties
are "defaulted" by default properties specified by section 16 of the
XSL Transformations (XSLT) W3C Recommendation. The properties that
were specifically set by the user or the stylesheet should be in the base
Properties list, while the XSLT default properties that were not
specifically set should be the default Properties list. Thus,
getOutputProperties().getProperty(String key) will obtain any
property in that was set by setOutputProperty(java.lang.String, java.lang.String)
,
setOutputProperties(java.util.Properties)
, in the stylesheet, or the default
properties, while
getOutputProperties().get(String key) will only retrieve properties
that were explicitly set by setOutputProperty(java.lang.String, java.lang.String)
,
setOutputProperties(java.util.Properties)
, or in the stylesheet.
Note that mutation of the Properties object returned will not effect the properties that the transformation contains.
If any of the argument keys are not recognized and are not namespace qualified, the property will be ignored. In other words the behaviour is not orthogonal with setOutputProperties.

Properties
public void setOutputProperty(java.lang.String name, java.lang.String value) throws java.lang.IllegalArgumentException
Pass a qualified property name as a two-part string, the namespace URI enclosed in curly braces ({}), followed by the local name. If the name has a null URL, the String only contain the local name. An application can safely check for a non-null URI by testing to see if the first character of the name is a '{' character.
For example, if a URI and local name were obtained from an element defined with <xyz:foo xmlns:xyz="http://xyz.foo.com/yada/baz.html"/>, then the qualified name would be "{http://xyz.foo.com/yada/baz.html}foo". Note that no prefix is used.
The Properties object that was passed to setOutputProperties(java.util.Properties)
won't
be effected by calling this method.
