public class AbsentExtensionElement extends StyleElement
This element is a surrogate for an extension element (or indeed an xsl element) for which no implementation is available.

  • Constructor Details

    • AbsentExtensionElement

      public AbsentExtensionElement()

  • Method Details

    • 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

    • isInstruction

      public boolean isInstruction()
      Description copied from class: StyleElement
      Ask whether this node is an instruction. The default implementation says it isn't.
      Overrides:
      isInstruction in class StyleElement
      Returns:
      true if this element is an instruction

    • mayContainSequenceConstructor

      protected boolean mayContainSequenceConstructor()
      Determine whether this type of element is allowed to contain a template-body
      Overrides:
      mayContainSequenceConstructor in class StyleElement
      Returns:
      true if this instruction is allowed to contain a sequence constructor

    • processAllAttributes

      public void processAllAttributes() throws XPathException
      Process the attributes of this element and all its children
      Overrides:
      processAllAttributes in class StyleElement
      Throws:
      XPathException - in the event of a static error being detected

    • 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

    • markTailCalls

      protected boolean markTailCalls()
      Mark tail-recursive calls on templates and functions. For most instructions, this does nothing.
      Overrides:
      markTailCalls in class StyleElement
      Returns:
      true if one or more tail calls were identified

    • validateSubtree

      public void validateSubtree(ComponentDeclaration decl, boolean excludeStylesheet) throws XPathException
      Recursive walk through the stylesheet to validate all nodes
      Overrides:
      validateSubtree in class StyleElement
      Parameters:
      decl - the declaration to be validated
      excludeStylesheet - true if the XSLStylesheet element is to be excluded
      Throws:
      XPathException - if validation fails

    • validate

      public void validate(ComponentDeclaration decl) 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
      Parameters:
      decl - the declaration to be validated
      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
