    • Method Detail

      • isInstruction

        public boolean isInstruction()
        Determine whether this node is an instruction.
        Overrides:
        isInstruction in class StyleElement
        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 class StyleElement
        Returns:
        the item type returned
      • mayContainSequenceConstructor

        public boolean mayContainSequenceConstructor()
        Determine whether this type of element is allowed to contain a template-body
        Overrides:
        mayContainSequenceConstructor in class StyleElement
        Returns:
        true: yes, it may contain a template-body
      • 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 class StyleElement
        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 class StyleElement
        Throws:
        XPathException
      • markTailCalls

        public void markTailCalls()
        Mark tail-recursive calls on stylesheet functions. For most instructions, this does nothing.
        Overrides:
        markTailCalls in class StyleElement
      • 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 class StyleElement
        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
