Method Detail

processExtensionElementAttribute

protected void processExtensionElementAttribute(int nc)
                                         throws 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 class StyleElement

Parameters:

nc - the name code of the attribute required (ignored)

Throws:

TransformerConfigurationException

prepareAttributes

public void prepareAttributes()
                       throws 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 class StyleElement

Throws:

TransformerConfigurationException

mayContainTemplateBody

public boolean mayContainTemplateBody()

Determine whether this type of element is allowed to contain a template-body

Overrides:

mayContainTemplateBody in class StyleElement

Returns:

true: yes, it may contain a template-body

validate

public void validate()
              throws 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 class StyleElement

Throws:

TransformerConfigurationException

preprocess

public void preprocess()
                throws 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 class StyleElement

Throws:

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 class StyleElement

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 TransformerException

Call this function

Throws:

TransformerException
