org.apache.xalan.transformer
Interface TransformState

All Known Implementing Classes:

ResultTreeHandler

public interface TransformState

This interface is meant to be used by a consumer of SAX2 events produced by Xalan, and enables the consumer to get information about the state of the transform. It is primarily intended as a tooling interface. A content handler can get a reference to a TransformState by implementing the TransformerClient interface. Xalan will check for that interface before it calls startDocument, and, if it is implemented, pass in a TransformState reference to the setTransformState method.

Note that the current stylesheet and root stylesheet can be retrieved from the ElemTemplateElement obtained from either getCurrentElement() or getCurrentTemplate().

Method Summary

org.w3c.dom.traversal.NodeIterator	getContextNodeList() Get the current context node list.
ElemTemplateElement	getCurrentElement() Retrieves the stylesheet element that produced the SAX event.
org.w3c.dom.Node	getCurrentNode() This method retrieves the current context node in the source tree.
ElemTemplate	getCurrentTemplate() This method retrieves the xsl:template that is in effect, which may be a matched template or a named template.
org.w3c.dom.Node	getMatchedNode() Retrieves the node in the source tree that matched the template obtained via getMatchedTemplate().
ElemTemplate	getMatchedTemplate() This method retrieves the xsl:template that was matched.
javax.xml.transform.Transformer	getTransformer() Get the TrAX Transformer object in effect.

Method Detail

getCurrentElement

public ElemTemplateElement getCurrentElement()

Retrieves the stylesheet element that produced the SAX event.

Please note that the ElemTemplateElement returned may be in a default template, and thus may not be defined in the stylesheet.

Returns:

the stylesheet element that produced the SAX event.

getCurrentNode

public org.w3c.dom.Node getCurrentNode()

This method retrieves the current context node in the source tree.

Returns:

the current context node in the source tree.

getCurrentTemplate

public ElemTemplate getCurrentTemplate()

This method retrieves the xsl:template that is in effect, which may be a matched template or a named template.

Please note that the ElemTemplate returned may be a default template, and thus may not have a template defined in the stylesheet.

Returns:

the xsl:template that is in effect

getMatchedTemplate

public ElemTemplate getMatchedTemplate()

This method retrieves the xsl:template that was matched. Note that this may not be the same thing as the current template (which may be from getCurrentElement()), since a named template may be in effect.

Please note that the ElemTemplate returned may be a default template, and thus may not have a template defined in the stylesheet.

Returns:

the xsl:template that was matched.

getMatchedNode

public org.w3c.dom.Node getMatchedNode()

Retrieves the node in the source tree that matched the template obtained via getMatchedTemplate().

Returns:

the node in the source tree that matched the template obtained via getMatchedTemplate().

getContextNodeList

public org.w3c.dom.traversal.NodeIterator getContextNodeList()

Get the current context node list.

Returns:

the current context node list.

getTransformer

public javax.xml.transform.Transformer getTransformer()

Get the TrAX Transformer object in effect.

Returns:

the TrAX Transformer object in effect.
