Method Detail

processExtensionElementAttribute
protected void processExtensionElementAttribute(int nc) throws javax.xml.transform.TransformerConfigurationException
Process the [xsl:]extension-element-prefixes attribute. This overrides the standard method because saxon:function and exslt:function implicitly declare saxon/exslt (respectively) as an extension namespace.- Overrides:
processExtensionElementAttribute
in classStyleElement
- Parameters:
nc
- the name code of the attribute required (ignored)- Throws:
javax.xml.transform.TransformerConfigurationException
-
prepareAttributes
public void prepareAttributes() throws javax.xml.transform.TransformerConfigurationException
Description copied from class:StyleElement
Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass- Specified by:
prepareAttributes
in classStyleElement
- Throws:
javax.xml.transform.TransformerConfigurationException
-
mayContainTemplateBody
public boolean mayContainTemplateBody()
Determine whether this type of element is allowed to contain a template-body- Overrides:
mayContainTemplateBody
in classStyleElement
- Returns:
- true: yes, it may contain a template-body
-
validate
public void validate() throws javax.xml.transform.TransformerConfigurationException
Description copied from class:StyleElement
Check that the element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.- Overrides:
validate
in classStyleElement
- Throws:
javax.xml.transform.TransformerConfigurationException
-
preprocess
public void preprocess() throws javax.xml.transform.TransformerConfigurationException
Description copied from class:StyleElement
Default preprocessing method does nothing. It is implemented for those top-level elements that can be evaluated before the source document is available, for example xsl:key, xsl:attribute-set, xsl:template, xsl:locale- Overrides:
preprocess
in classStyleElement
- Throws:
javax.xml.transform.TransformerConfigurationException
-
process
public void process(Context context)
Description copied from class:StyleElement
Process: called to do the real work of this stylesheet element. This method must be implemented in each subclass.- Specified by:
process
in classStyleElement
- Parameters:
context
- The context in the source XML document, giving access to the current node, the current variables, etc.
-
getProcedure
public Procedure getProcedure()
Get associated Procedure (for details of stack frame)
-
getFunctionFingerprint
public int getFunctionFingerprint()
-
getNthParameter
public int getNthParameter(int n)
Get the name fingerprint of the n'th parameter (starting from 0). Return -1 if there is none such.
-
call
public Value call(ParameterSet params, Context context) throws javax.xml.transform.TransformerException
Call this function- Throws:
javax.xml.transform.TransformerException
