  • 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).
      Returns:
      the item type returned
    • mayContainSequenceConstructor

      protected boolean mayContainSequenceConstructor()
      Determine whether this type of element is allowed to contain a sequence constructor
      Overrides:
      mayContainSequenceConstructor in class StyleElement
      Returns:
      true: yes, it may contain a sequence constructor
    • prepareAttributes

      protected void prepareAttributes()
      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
    • compile

      public Expression compile(Compilation exec, ComponentDeclaration decl) throws XPathException
      Description copied from class: StyleElement
      Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.
      Overrides:
      compile in class StyleElement
      Parameters:
      exec - the compilation episode
      decl - the containing top-level declaration, for example xsl:function or xsl:template
      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 - if validation fails
