TransformerFactory

java.lang.Object
- javax.xml.transform.TransformerFactory

Direct Known Subclasses:

SAXTransformerFactory
```
public abstract class TransformerFactory
extends java.lang.Object
```
A TransformerFactory instance can be used to create Transformer and Template objects.
The system property that determines which Factory implementation to create is named "javax.xml.transform.TransformerFactory". This property names a concrete subclass of the TransformerFactory abstract class. If the property is not defined, a platform default is be used.

  - newInstance
```
public static TransformerFactory newInstance()
                                      throws TransformerFactoryConfigurationError
```
    Obtain a new instance of a TransformerFactory. This static method creates a new factory instance This method uses the following ordered lookup procedure to determine the TransformerFactory implementation class to load:
    - Use the javax.xml.parsers.DocumentBuilderFactory system property.
    - Use the JAVA_HOME(the parent directory where jdk is installed)/lib/jaxp.properties for a property file that contains the name of the implementation class keyed on the same value as the system property defined above.
    - Use the Services API (as detailed in teh JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.parsers.TransformerFactory in jars available to the runtime.
    - Platform default TransformerFactory instance.
    Once an application has obtained a reference to a TransformerFactory it can use the factory to configure and obtain parser instances.
    Returns:
    
    new TransformerFactory instance, never null.
    
    Throws:
    
    TransformerFactoryConfigurationError - if the implmentation is not available or cannot be instantiated.
  - newTransformer
```
public abstract Transformer newTransformer(Source source)
                                    throws TransformerConfigurationException
```
    Process the Source into a Transformer object. Care must be given not to use this object in multiple threads running concurrently. Different TransformerFactories can be used concurrently by different threads.
    
    Parameters:
    
    source - An object that holds a URI, input stream, etc.
    
    Returns:
    
    A Transformer object that may be used to perform a transformation in a single thread, never null.
    
    Throws:
    
    TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.
  - newTransformer
```
public abstract Transformer newTransformer()
                                    throws TransformerConfigurationException
```
    Create a new Transformer object that performs a copy of the source to the result.
    
    Parameters:
    
    source - An object that holds a URI, input stream, etc.
    
    Returns:
    
    A Transformer object that may be used to perform a transformation in a single thread, never null.
    
    Throws:
    
    TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.
  - newTemplates
```
public abstract Templates newTemplates(Source source)
                                throws TransformerConfigurationException
```
    Process the Source into a Templates object, which is a a compiled representation of the source. This Templates object may then be used concurrently across multiple threads. Creating a Templates object allows the TransformerFactory to do detailed performance optimization of transformation instructions, without penalizing runtime transformation.
    
    Parameters:
    
    source - An object that holds a URL, input stream, etc.
    
    Returns:
    
    A Templates object capable of being used for transformation purposes, never null.
    
    Throws:
    
    TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.
  - getAssociatedStylesheet
```
public abstract Source getAssociatedStylesheet(Source source,
                                               java.lang.String media,
                                               java.lang.String title,
                                               java.lang.String charset)

```
    Get the stylesheet specification(s) associated via the xml-stylesheet processing instruction (see http://www.w3.org/TR/xml-stylesheet/) with the document document specified in the source parameter, and that match the given criteria. Note that it is possible to return several stylesheets, in which case they are applied as if they were a list of imports or cascades in a single stylesheet.
    
    Parameters:
    
    source - The XML source document.
    
    media - The media attribute to be matched. May be null, in which case the prefered templates will be used (i.e. alternate = no).

    A Source object suitable for passing to the TransformerFactory.
    
    Throws:
    
    TransformerConfigurationException.
