Constructor Detail

ElemFallback

public ElemFallback()

Method Detail

getXSLToken

public int getXSLToken()

Get an int constant identifying the type of element.

Overrides:

getXSLToken in class ElemTemplateElement

Returns:

The token ID for this element

See Also:

Constants

getNodeName

public String getNodeName()

Return the node name.

Specified by:

getNodeName in interface org.w3c.dom.Node

Overrides:

getNodeName in class ElemTemplateElement

Returns:

The Element's name

execute

public void execute(TransformerImpl transformer)
             throws javax.xml.transform.TransformerException

This is the normal call when xsl:fallback is instantiated. In accordance with the XSLT 1.0 Recommendation, chapter 15, "Normally, instantiating an xsl:fallback element does nothing."

Overrides:

execute in class ElemTemplateElement

Parameters:

transformer - non-null reference to the the current transform-time state.

Throws:

javax.xml.transform.TransformerException

executeFallback

public void executeFallback(TransformerImpl transformer)
                     throws javax.xml.transform.TransformerException

Execute the fallback elements. This must be explicitly called to instantiate the content of an xsl:fallback element. When an XSLT transformer performs fallback for an instruction element, if the instruction element has one or more xsl:fallback children, then the content of each of the xsl:fallback children must be instantiated in sequence; otherwise, an error must be signaled. The content of an xsl:fallback element is a template.

Parameters:

transformer - non-null reference to the the current transform-time state.

Throws:

javax.xml.transform.TransformerException
