int	getResultIndex() Provides the EXSLT extension handler access to the return value.
int	getXSLToken() Get an integer representation of the element type.
(package private) void	setResultIndex(int stackIndex) Sets aside a position on the local variable stack index to refer to the result element return value.

Field Detail

_resultIndex

private int _resultIndex

Add the namespace to the StylesheetRoot vector of extension namespaces. Be sure the exslt:function namespace is also added.

Constructor Detail

ElemExsltFunction

public ElemExsltFunction()

Method Detail

getXSLToken

public int getXSLToken()

Get an integer representation of the element type.

Overrides:

getXSLToken in class ElemTemplate

Returns:

An integer representation of the element, defined in the Constants class.

See Also:

Constants

getNodeName

public String getNodeName()

Return the node name, defined in the Constants class.

Specified by:

getNodeName in interface org.w3c.dom.Node

Overrides:

getNodeName in class ElemTemplate

Returns:

The node name

See Also:

org.apache.xalan.templates.Constants.

execute

public void execute(TransformerImpl transformer,
                    XObject[] args)
             throws javax.xml.transform.TransformerException

Throws:

javax.xml.transform.TransformerException

compose

public void compose(StylesheetRoot sroot)
             throws javax.xml.transform.TransformerException

Called after everything else has been recomposed, and allows the function to set remaining values that may be based on some other property that depends on recomposition. Also adds a slot to the variable stack for the return value. The result element will place its value in this slot.

Overrides:

compose in class ElemTemplate

Throws:

javax.xml.transform.TransformerException

setResultIndex

void setResultIndex(int stackIndex)

Sets aside a position on the local variable stack index to refer to the result element return value.

getResultIndex

public int getResultIndex()

Provides the EXSLT extension handler access to the return value.
