Nested Class Summary

protected static class	ER7.ER7SegmentHandler
protected static interface	ER7.Handler

Method Summary

static void	main(String[] args)
static boolean	parseMessage(Properties props, List<DatumPath> msgMask, String message) Parses message and dumps contents to props, with keys in the ZYX[a]-b[c]-d-e style.
protected static boolean	parseMSHSegmentWhole(Properties props, List<DatumPath> msgMask, EncodingCharacters encodingChars, String segment) given segment, starting with "MSH", then encoding characters, etc...
protected static void	parseSegmentGuts(ER7.Handler handler, String guts, List<Integer> nodeKey) recursively tokenize "guts" (a segment, or part of one) into tokens, according to separators (aka delimiters) which are different at each level of recursion, and to a recursive depth which is discovered through "handler" via handler.delim(int) and handler.specDepth() As tokens are found, they are reported to handler via handler.putDatum(), which presumably stashes them away somewhere.
protected static void	parseSegmentWhole(Properties props, Map<String,Integer> segmentId2nextRepIdx, List<DatumPath> msgMask, EncodingCharacters encodingChars, String segment) pass in a whole segment (of type other than MSH), including message type at the start, according to encodingChars, and we'll parse the contents and put them in props.

Method Detail

parseMessage

public static boolean parseMessage(Properties props,
                                   List<DatumPath> msgMask,
                                   String message)

Parses message and dumps contents to props, with keys in the ZYX[a]-b[c]-d-e style.

parseMSHSegmentWhole

protected static boolean parseMSHSegmentWhole(Properties props,
                                              List<DatumPath> msgMask,
                                              EncodingCharacters encodingChars,
                                              String segment)

given segment, starting with "MSH", then encoding characters, etc... put MSH[0]-1[0]-1-1 (== MSH-1) and MSH[0]-2[0]-1-1 (== MSH-2) into props, if found, plus everything else found in 'segment'

parseSegmentWhole

protected static void parseSegmentWhole(Properties props,
                                        Map<String,Integer> segmentId2nextRepIdx,
                                        List<DatumPath> msgMask,
                                        EncodingCharacters encodingChars,
                                        String segment)

pass in a whole segment (of type other than MSH), including message type at the start, according to encodingChars, and we'll parse the contents and put them in props.

parseSegmentGuts

protected static void parseSegmentGuts(ER7.Handler handler,
                                       String guts,
                                       List<Integer> nodeKey)

recursively tokenize "guts" (a segment, or part of one) into tokens, according to separators (aka delimiters) which are different at each level of recursion, and to a recursive depth which is discovered through "handler" via handler.delim(int) and handler.specDepth() As tokens are found, they are reported to handler via handler.putDatum(), which presumably stashes them away somewhere. We tell the handler about the location in the message via putDatum()'s key argument, which is a List of Integers representing the position in the parse tree (size() == depth of recursion). TODO: say more.
