    Constant Field Values

### m_optimize

    public static boolean m_optimize

### m_source_location

    public static boolean m_source_location

  Flag set by FEATURE_SOURCE_LOCATION. This feature specifies whether the transformation phase should keep track of line and column numbers for the input source document. Note that this works only when that information is available from the source -- in other words, if you pass in a DOM, there's little we can do for you. The default is false. Setting it true may significantly increase storage cost per node.

Method Detail

### processFromNode

    public Templates processFromNode(Node node)
                              throws TransformerConfigurationException

  Throws:
    `TransformerConfigurationException`

### getAssociatedStylesheet

    public Source getAssociatedStylesheet(Source source,
                                          java.lang.String media,
                                          java.lang.String title,
                                          java.lang.String charset)
                                   throws TransformerConfigurationException

  Get InputSource specification(s) that are associated with the given document specified in the source param, via the xml-stylesheet processing instruction (see http://www.w3.org/TR/xml-stylesheet/), and that matches the given criteria. Note that it is possible to return several stylesheets that match the criteria, in which case they are applied as if they were a list of imports or cascades.

  Note that DOM2 has it's own mechanism for discovering stylesheets. Therefore, there isn't a DOM version of this method.

  Specified by:
    `getAssociatedStylesheet` in class `TransformerFactory`
  Parameters:
    `source` - The XML source that is to be searched.
    `media` - The media attribute to be matched. May be null, in which case the prefered templates will be used (i.e. alternate = no).
    `title` - The value of the title attribute to match. May be null.
    `charset` - The value of the charset attribute to match. May be null.
  Returns:
    A Source object capable of being used to create a Templates object.
  Throws:
    `TransformerConfigurationException`

### newTemplatesHandler

    public TemplatesHandler newTemplatesHandler()
                                         throws TransformerConfigurationException

  Create a new Transformer object that performs a copy of the source to the result.

  Specified by:
    `newTemplatesHandler` in class `SAXTransformerFactory`
  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.

### getFeature

    public boolean getFeature(java.lang.String name)

  Look up the value of a feature.

  The feature name is any fully-qualified URI. It is possible for an TransformerFactory to recognize a feature name but to be unable to return its value; this is especially true in the case of an adapter for a SAX1 Parser, which has no way of knowing whether the underlying parser is validating, for example.

  Specified by:
    `getFeature` in class `TransformerFactory`
  Parameters:
    `name` - The feature name, which is a fully-qualified URI.
  Returns:
    The current state of the feature (true or false).

  Specified by:
    `setAttribute` in class `TransformerFactory`
  Parameters:
    `name` - The name of the attribute.
    `value` - The value of the attribute; Boolean or String="true"|"false"
  Throws:
    `java.lang.IllegalArgumentException` - thrown if the underlying implementation doesn't recognize the attribute.

### getAttribute

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

  Allows the user to retrieve specific attributes on the underlying implementation.

  Specified by:
    `getAttribute` in class `TransformerFactory`
  Parameters:
    `name` - The name of the attribute.
  Returns:
    value The value of the attribute.
  Throws:
    `java.lang.IllegalArgumentException` - thrown if the underlying implementation doesn't recognize the attribute.

### newXMLFilter
