Method Detail
-
isInstruction
public boolean isInstruction()
Determine whether this node is an instruction.- Overrides:
isInstruction
in classStyleElement
- Returns:
- true - it is an instruction
-
getReturnedItemType
protected ItemType getReturnedItemType()
Determine the type of item returned by this instruction (only relevant if it is an instruction).- Overrides:
getReturnedItemType
in classStyleElement
- Returns:
- the item type returned
-
prepareAttributes
public void prepareAttributes() throws XPathException
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:
XPathException
-
validate
public void validate() throws XPathException
Description copied from class:StyleElement
Check that the stylesheet 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:
XPathException
-
markTailCalls
public void markTailCalls()
Mark tail-recursive calls on templates and functions.- Overrides:
markTailCalls
in classStyleElement
-
compile
public Expression compile(Executable exec) throws XPathException
Description copied from class:StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.- Specified by:
compile
in classStyleElement
- Returns:
- either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.
- Throws:
XPathException
