public class Udom2Sax extends SinglePhase_rt
Generates SAX events in name-space mode. Create an instance (always anew, no resuage) and then call convert(eu.bandm.tools.message.MessageReceiver<eu.bandm.tools.message.SimpleMessage<?>>,org.xml.sax.ContentHandler,eu.bandm.tools.d2d2.rt.ResultingStructure,@eu.bandm.tools.annotations.Opt java.util.Map<java.lang.String,java.lang.String>)- Has to be piped into a consuming ContentHandler in name-space mode, like NamespaceEmbedder.
An ooption LexicalHandler is for comments and PIs.

    • lastCharsWritten

    • cachedLocation

      protected Location<String> cachedLocation

    • locator

      protected final Locator locator

    • attributesDone

      protected Set<Definition> attributesDone
      All those definitions the content of which (under the currently written node) have already been written out as attributes, and therefore do not need further processing.

    • msg

      protected MessageReceiver<SimpleMessage<?>> msg
      Target of all error messages. Currently only reflection generated exception (when a post processor cannot be found) or from the sax receiver (SAXExceptions) can happen.

    • sax

      protected ContentHandler sax
      Target of generated write-out.

    • saxlex

      protected LexicalHandler saxlex
      Target of generated comments and pis.

    • toplevelStructure

      protected ResultingStructure toplevelStructure
      Diagnosis only.

    • ws_buffer

      protected final List<ResultingChars> ws_buffer
      Accumulator for whitespace which will be written out iff non-white-space character data follows.

    • trimming

      protected boolean trimming
      Whether there is any whitespace trimming, as determined by the node type declaration. If true, then whitespace character data will at most be put into the intermediate buffer, and written out only when non-white-space data follows.

    • trimfirst

      protected boolean trimfirst
      Indicates that no non-white-space character data has appeared yet, and (if trimming) whitespace is NOT written to ws_buffer.

    • convert

      public void convert(MessageReceiver<SimpleMessage<?>> msg, ContentHandler sax, ResultingStructure structure, @Opt @Opt Map<String,String> namespaceContext)
      Top-level entry point. No special constructor required! All uris in namespaceContext are added to the output context, the prefix therein is used iff (1) uri not yet defined, (2) if prefix used, it will be mangled. Used primely for xslt source namespaces, which are present only in xpath expressions! THEREFORE IT CAN FAIL BECAUSE MANGLING OF PREFIXES DOES NOT CARRY OVER as long as xslt/xpath is external/unparsed!
      Parameters:
      msg - target for error messages when trying to write the SAX event. (All these messages are due to technical reasons and do not carry a location information.)
      sax - target for the SAX events.
      structure - what to write out.
      namespaceContext - map of prefices to uris, output at first, may be ==null.

    • ws_buffer_flush

      protected void ws_buffer_flush()
      Called when writing out any non-whitespace character data, or when starting an "open" tag.

    • checknamespace

      protected void checknamespace(NamespaceName n, boolean isAttribute) throws SAXException
      Generate an SAX call, iff the namespace uri is not yet mapped to a prefix, and memoize. Otherwise do nothing, so that the current (second) prefix (=synonym) will be ignored and the oldest assigned prefix continued to be used.
      Throws:
      SAXException

    • marknamespace

      protected int marknamespace()
      Remember the number of currently mapped name spaces.

    • releasenamespace

      protected void releasenamespace(int level) throws SAXException
      Close all namespaces, as they were at the beginning of the element
      Throws:
      SAXException

    • getCharOnly

      protected String getCharOnly(ResultContainer c)

    • action

      public void action(ResultingStructure res_pre)
      If argument is not yet written out as attribute, then (1) apply postproc, (2) collect all attributes, (3) emit an "open element" sax event, (4) visit sub-structure, (5) emit a "close element" sax event.
