eu.bandm.tools.xslt.tdom.Visitor

Type Parameters:
N - the node type of the input dom.
All Implemented Interfaces:
PCDataVisitor
public class Application<N> extends CombinedVisitor
Each instance of this class realizes the application of an xslt program, given as a Transformation, to a certain input. The constructor must be called, and then execute(), which returns the result either as one single TypedSubstantial, or as a MultiTypeNodeList, (but of course containing no more xslt elements but only Result Tree Fragments).
The real evaluation is nothing more than
  1. step through all MultiTypeNodeLists, thereby
    (a) copying all result type constants found into a result buffer,
    and (b) the results of evaluating all xslt commands.
  2. additionally, an xslt command can be replaced by its result iff its frequency is lower than "always".
  3. reduce the MultiTypeNodeList to a result type tdom element (which implies type checking).
  4. continuing so bottom-up
As preparatory step, all MultiTypeNodeLists which have mixed frequency are rewritten, so that they can be updated without disturbing the original Transformation object (esp. its Map "result_subtrees")
FIXME check expression CACHE (general expression cache) vs atribnameonlyonce
FIXME generation of TEXT ONLY (resultContext==null) missing.
FIXME OWN "pedantic" for Transformation and Application !?!? DISLOC [XSLT 1.0:14.2] defines NamespaceNames for extension functions

    • execute

      public MultiTypeNodeList execute()
      Top-level call for the start element. (initial_context is already set up.) FIXME result should be checked for unity !?!?

    • singleResultElement

      @Opt public @Opt TypedElement singleResultElement()

    • rewriteMixedBlocks

      void rewriteMixedBlocks()
      Preparation step which copies the code iff necessary. Basic aim is that blocks with frequency = "once" can be REPLACED by their evaluation result (appearing as a "const" block) without damaging the original code. Therefore a toplevel "once" block or all "mixed" blocks atop of a "once" must be copied. Blocks with frequ "always" must always be executed and the original code can be shared between applications. Blocks with frequ "constant" COULD already have been eliminated when type checking, but this would imply a different strictness strategy! Currently they are treated like "once".

      Can be overridden by the user to define particular semantic operations. Will be called whenever the default model instance traversal (as implemented by the methods in this class) reaches such an element.

      public void visit(eu.bandm.tools.xslt.tdom.Element_xsl_template el)
      Executed after a call-template (caller!=null) or apply-templates.
      FIXME ersteres kann kurzgeschlossen werden !?!? Preparations of parameters is stored in callState. In the first case all undeclared with-params are suppressed by static analysis (only "template2params.get(el)" are processed.) // FIXME this case should be INLINED (no visit() necessary) This is different with apply-templates: Undeclared with-params must be eliminated for each template differently, for not to shadow globals. The resulting bindings are constant per template and apply-templates execution and are cached in callstate. Default values for declared but not supplied parameters must be calculated in both cases. (They may depend on the current focus, which in case of caller==null is VARYING!)

    • visit

      public void visit(eu.bandm.tools.xslt.tdom.Element_xsl_text el)
      Deliver text contents, or start a sub-parser for "disabled output escaping".

    • visit

      public void visit(eu.bandm.tools.xslt.tdom.Element_xsl_value_of el)
      Implements [XSLT 1.0:7.6.1] "The xsl:value-of element is instantiated to create a text node in the result tree. The required select attribute is an expression; this expression is evaluated and the resulting object is converted to a string as if by a call to the string function."
      "disable output escaping" is realized by parsing the text as if it was in an original input document, see feedTextToResult(Element,String) ("general entities" are not considered ? FIXME)

      protected void feedTextToResult(eu.bandm.tools.xslt.tdom.Element el, String text)
      ATTENTION :
      (1) Assume only relatively SMALL text, so all sax events are collected statically / thread-less in ONE Queue.
      (2) numeric character references "&#...;" should be resolved on parsing . (3) namespace start/end mapping prefices not yet correctly handled (4) namespace resolution unclear !?!?!?
