Class TransformerIdentityImpl

java.lang.Object
  javax.xml.transform.Transformer
      org.apache.xalan.transformer.TransformerIdentityImpl

All Implemented Interfaces:

javax.xml.transform.sax.TransformerHandler, org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.ext.DeclHandler, org.xml.sax.ext.LexicalHandler

public class TransformerIdentityImpl
extends javax.xml.transform.Transformer
implements javax.xml.transform.sax.TransformerHandler, org.xml.sax.ext.DeclHandler

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.

createResultContentHandler

private void createResultContentHandler(javax.xml.transform.Result outputTarget)
                                 throws javax.xml.transform.TransformerException

Create a result ContentHandler from a Result object, based on the current OutputProperties.

Parameters:

outputTarget - Where the transform result should go, should not be null.

Throws:

javax.xml.transform.TransformerException

transform

public void transform(javax.xml.transform.Source source,
                      javax.xml.transform.Result outputTarget)
               throws javax.xml.transform.TransformerException

Process the source tree to the output result.

Specified by:

transform in class javax.xml.transform.Transformer

Parameters:

source - The input for the source tree.

outputTarget - The output target.

Throws:

javax.xml.transform.TransformerException - If an unrecoverable error occurs during the course of the transformation.

setParameter

public void setParameter(java.lang.String name,
                         java.lang.Object value)

Add a parameter for the transformation.

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.

Specified by:

setParameter in class javax.xml.transform.Transformer

Parameters:

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.

getParameter

public java.lang.Object getParameter(java.lang.String name)

Get a parameter that was explicitly set with setParameter or setParameters.

This method does not return a default parameter value, which cannot be determined until the node context is evaluated during the transformation process.

Specified by:

getParameter in class javax.xml.transform.Transformer

Parameters:

name - Name of the parameter.

Returns:

A parameter that has been set with setParameter.

clearParameters

public void clearParameters()

Clear all parameters set with setParameter.

Specified by:

clearParameters in class javax.xml.transform.Transformer

setURIResolver

public void setURIResolver(javax.xml.transform.URIResolver resolver)

Set an object that will be used to resolve URIs used in document().

If the resolver argument is null, the URIResolver value will be cleared, and the default behavior will be used.

Specified by:

setURIResolver in class javax.xml.transform.Transformer

Parameters:

resolver - An object that implements the URIResolver interface, or null.

getURIResolver

public javax.xml.transform.URIResolver getURIResolver()

Get an object that will be used to resolve URIs used in document(), etc.

Specified by:

getURIResolver in class javax.xml.transform.Transformer

Returns:

An object that implements the URIResolver interface, or null.

setOutputProperties

public void setOutputProperties(java.util.Properties oformat)
                         throws java.lang.IllegalArgumentException

Set the output properties for the transformation. These properties will override properties set in the Templates with xsl:output.

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.

Specified by:

setOutputProperties in class javax.xml.transform.Transformer

Parameters:

oformat - A set of output properties that will be used to override any of the same properties in affect for the transformation.

Throws:

java.lang.IllegalArgumentException - if any of the argument keys are not recognized and are not namespace qualified.

See Also:

OutputKeys, Properties

getOutputProperties

public java.util.Properties getOutputProperties()

Get a copy of the output properties for the transformation.

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.

Specified by:

getOutputProperties in class javax.xml.transform.Transformer

Returns:

A copy of the set of output properties in effect for the next transformation.

See Also:

OutputKeys, Properties

setOutputProperty

public void setOutputProperty(java.lang.String name,
                              java.lang.String value)
                       throws java.lang.IllegalArgumentException

Set an output property that will be in effect for the transformation.

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.

Specified by:

setOutputProperty in class javax.xml.transform.Transformer

Parameters:

name - A non-null String that specifies an output property name, which may be namespace qualified.

value - The non-null string value of the output property.

                                   throws java.lang.IllegalArgumentException

Get an output property that is in effect for the transformation. The property specified may be a property that was set with setOutputProperty, or it may be a property specified in the stylesheet.

Specified by:

getOutputProperty in class javax.xml.transform.Transformer

Parameters:

name - A non-null String that specifies an output property name, which may be namespace qualified.

Returns:

The string value of the output property, or null if no property was found.
