Constructor Detail

XSLIf

public XSLIf()
Method Detail

isInstruction

public boolean isInstruction()
Determine whether this node is an instruction.

Overrides:
isInstruction in class StyleElement
Returns:
true - it is an instruction

doesPostProcessing

public boolean doesPostProcessing()
Determine whether this element does any processing after instantiating any children. This implementation says it doesn't, thus enabling tail recursion.

Overrides:
doesPostProcessing in class StyleElement

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

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

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

process

public void process(Context context)
             throws TransformerException
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.
Throws:
TransformerException
