Constant Field Values

m_DOMsystemID

private String m_DOMsystemID
The systemID that was specified in processFromNode(Node node, String systemID).


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. %REVIEW% SAX2DTM is explicitly reaching up to retrieve this global field. We should instead have an architected pathway for passing hints of this sort down from TransformerFactory to Transformer to DTMManager to DTM.


m_uriResolver

javax.xml.transform.URIResolver m_uriResolver
The object that implements the URIResolver interface, or null.


m_errorListener

private javax.xml.transform.ErrorListener m_errorListener
The error listener.

Throws:
javax.xml.transform.TransformerConfigurationException

getDOMsystemID

String getDOMsystemID()
The systemID that was specified in processFromNode(Node node, String systemID).

Returns:
The systemID, or null.

processFromNode

javax.xml.transform.Templates processFromNode(org.w3c.dom.Node node,
                                              String systemID)

Process the stylesheet from a DOM tree, if the processor supports the "http://xml.org/trax/features/dom/input" feature.

Parameters:
node - A DOM tree which must contain valid transform instructions that this processor understands.
systemID - The systemID from where xsl:includes and xsl:imports should be resolved from.
Returns:
A Templates object capable of being used for transformation purposes.
Throws:
javax.xml.transform.TransformerConfigurationException

public javax.xml.transform.Source getAssociatedStylesheet(javax.xml.transform.Source source,
                                                          String media,
                                                          String title,
                                                          String charset)
                                                   throws javax.xml.transform.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.

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:
javax.xml.transform.TransformerConfigurationException

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

Returns:
A Transformer object that may be used to perform a transformation in a single thread, never null.
Throws:
javax.xml.transform.TransformerConfigurationException - May throw this during the parse when it is constructing the Templates object and fails.

getFeature

public boolean getFeature(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.

Parameters:
name - The feature name, which is a fully-qualified URI.
Returns:
The current state of the feature (true or false).

setAttribute

public void setAttribute(String name,
                         Object value)
                  throws IllegalArgumentException
Allows the user to set specific attributes on the underlying implementation.

Parameters:
name - The name of the attribute.
value - The value of the attribute; Boolean or String="true"|"false"
Throws:
IllegalArgumentException - thrown if the underlying implementation doesn't recognize the attribute.

getAttribute

public Object getAttribute(String name)
                    throws IllegalArgumentException
Allows the user to retrieve specific attributes on the underlying implementation.

Parameters:
name - The name of the attribute.
Returns:
value The value of the attribute.
