m_DOMsystemID

private java.lang.String m_DOMsystemID

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

m_optimize

private boolean m_optimize

Flag set by FEATURE_OPTIMIZE. This feature specifies whether to Optimize stylesheet processing. By default it is set to true.

m_source_location

private 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.

m_incremental

private boolean m_incremental

Flag set by FEATURE_INCREMENTAL. This feature specifies whether to produce output incrementally, rather than waiting to finish parsing the input before generating any output. By default this attribute is set to false.

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.

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 javax.xml.transform.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.

Specified by:

newTemplatesHandler in class javax.xml.transform.sax.SAXTransformerFactory

Set a feature for this TransformerFactory and Transformers or Templates created by this factory.

Feature names are fully qualified URIs. Implementations may define their own features. An TransformerConfigurationException is thrown if this TransformerFactory or the Transformers or Templates it creates cannot support the feature. It is possible for an TransformerFactory to expose a feature value but be unable to change its state.

See TransformerFactory for full documentation of specific features.

Specified by:

setFeature in class javax.xml.transform.TransformerFactory

Parameters:

name - Feature name.

value - Is feature state true or false.

Throws:

java.lang.NullPointerException - If the name parameter is null.

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 javax.xml.transform.TransformerFactory

Parameters:

name - The feature name, which is a fully-qualified URI.

Returns:

The current state of the feature (true or false).
