      Return the list of mode names to which this template rule is applicable.

      the list of mode names. If the mode attribute is absent, #default is assumed. If #default is present explicitly or implicitly, it is replaced by the default mode, taken from the in-scope default-modes attribute, which defaults to #unnamed. The unnamed mode is represented by Mode.UNNAMED_MODE_NAME. The token #all translates to Mode.OMNI_MODE_NAME.

    • 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
    • validateSubtree

      public void validateSubtree(ComponentDeclaration decl, boolean excludeStylesheet) throws XPathException
      Description copied from class: StyleElement
      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
    • index

      public void index(ComponentDeclaration decl, PrincipalStylesheetModule top)

      Overrides:
      index in class StyleElement
      Parameters:
      decl - the Declaration being indexed. (This corresponds to the StyleElement object except in cases where one module is imported several times with different precedence.)
      top - represents the outermost XSLStylesheet or XSLPackage element
    • markTailCalls

      protected boolean markTailCalls()
      Mark tail-recursive calls on templates and functions.
      Overrides:
      markTailCalls in class StyleElement
      Returns:
      true if one or more tail calls were identified
    • compileDeclaration

      public void compileDeclaration(Compilation compilation, ComponentDeclaration decl) throws XPathException
      Compile: creates the executable form of the template
      Overrides:
      compileDeclaration in class StyleElement
      Parameters:
      compilation - the compilation episode
      decl - the containing top-level declaration, for example xsl:function or xsl:template
      Throws:
      XPathException - if compilation fails
    • compileTemplateRule

      public void compileTemplateRule(Compilation compilation, Expression body)
    • jitCompile

      public void jitCompile(Compilation compilation, ComponentDeclaration decl) throws XPathException
      Code executed when the template is first executed under JIT. If the template is defined in several modes, then this may be called several times, but it only does anything the first time. Mode-specific processing is done in the TemplateRuleInitializer.
      Parameters:
      compilation - the compilation episode
      decl - the template rule declaration
      Throws:
      XPathException - if anything goes wrong
    • register

      public void register(ComponentDeclaration declaration) throws XPathException
      Registers the template rule with each Mode that it belongs to.
      Parameters:
      declaration - Associates this template with a stylesheet module (in principle an xsl:template element can be in a document that is imported more than once; these are separate declarations)
      Throws:
      XPathException - if a failure occurs
    • allocatePatternSlotNumbers

      public void allocatePatternSlotNumbers()
      Allocate slot numbers to any local variables declared within a predicate within the match pattern
    • optimize

      public void optimize(ComponentDeclaration declaration) throws XPathException
      This method is a bit of a misnomer, because it does more than invoke optimization of the template body. In particular, it also registers the template rule with each Mode that it belongs to.
      Specified by:
      optimize in interface StylesheetComponent
      Parameters:
      declaration - Associates this template with a stylesheet module (in principle an xsl:template element can be in a document that is imported more than once; these are separate declarations)
      Throws:
      XPathException - if errors are found
