public final class XSLSequence extends StyleElement
An xsl:sequence element in the stylesheet.
The xsl:sequence element takes attributes:
  • a mandatory attribute select="expression".

      public XSLSequence()

  • Method Details

    • 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

    • mayContainFallback

      public boolean mayContainFallback()
      Determine whether this type of element is allowed to contain an xsl:fallback instruction
      Overrides:
      mayContainFallback in class StyleElement

    • 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(int nameCode, int arity)
      Mark tail-recursive calls on templates and functions.

    • compile

      public Expression compile(Executable exec)
      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.
