  • Method Details

    • 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

    • isInstruction

      public boolean isInstruction()
      Determine whether this node is an instruction.
      Overrides:
      isInstruction in class StyleElement
      Returns:
      true - it is an instruction

    • isInXsltNamespace

      public boolean isInXsltNamespace()
      Ask whether the element is in the XSLT namespace
      Overrides:
      isInXsltNamespace in class StyleElement
      Returns:
      true if the element is in the XSLT namespace

    • validate

      public void validate(ComponentDeclaration decl) throws XPathException
      Description copied from class: XSLGeneralVariable
      Check that the variable is not already declared, and allocate a slot number
      Overrides:
      validate in class XSLGeneralVariable
      Parameters:
      decl - the declaration being validated. A single XSLVariableDeclaration object may represent multiple declarations if it appears in a stylesheet module that is included/imported more than once
      Throws:
      XPathException - if any error is found during validation

    • 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
