Subject: [U2] UOJ and value-mark and field-mark
I have a very simple file-TESTS, which only has 4 fields: @ID field, F1, F2
and F3. F1 is a single value field, F2 is a multi-value field and the value
is one value-mark-separated list, F3 is a single value field. It has the
following sample record in the file:
Field Name Value
@ID t101
F1 F1V1
F2 F2V1:@VM:F2V2
F3 F3V1
I use the following UniObject for Java code segment to retrieve the record
"t101" from the file:
//uSession is a UniSession Oject
uSession.connect();
//Open a file variable to TESTS file.
UniFile testFile = uSession.open("TESTS");
//Read the record out
String key = "t101";
UniStirng uString = personFile.read(key);
System.out.println(b the full record:b +uString);
System.out.println(b the number of fields in the file:b +uString.dcount());
When I print out the contents of the record, it looks like UOJ converts all
the value marks at the field F2 into the field mark. When I use dcount()
function to count the number of fields in the output, it returns 5, instead
of 4. I think the correct result should be 4 since only 4 fields (@ID
field, F1, F2 and F3) in the file. It seems that read() function converts
all the value-marks into the field-marks. So the values at the field-F2:
F2V1:@VM:F2V2 becomes F2:@FM:F2V2. That is why I got 5 instead of 4 when we
use dcount() to count the number of fields in the output.
We are running Unidata 7.1 in Red hat Linux server. I already set the
environment variable LANG to bCb. I even tried to set LANG to ben_USb. Both
times, the UOJ program returned the same result.
Does anyone know how this happens? I want to keep the original value-marks
and field-marks after using read() function. Please advice.
