How to check if date uses 1904 windowing with Apache POI XSSF eventmodel -


i writing program imports xlsx files apache poi eventmodel (sax/xssf). done, can't correct dates.

i parsing cell date value

<c r="d1" s="1">     <v>41319.558333333334</v> </c>

i using org.apache.poi.ss.usermodel.dateutil class date:

dateutil.getjavacalendar(doble date, bool use1904windowing);

what should pass use1904windowing correct dates? temporarily use false, gives me correct dates test workbook, know should read value somewhere.

there record datewindow1904record in binary xls format, read using hssf. counterpart in xssf? or should use false?

edit: @rgettman answer pointed me solution, it's not complete. in event model not have xssfworkbook object , can't getctworkbook() of it.

instead can create ctworkbook directly form inputstream:

opcpackage pkg = opcpackage.open(filename); xssfreader r = new xssfreader( pkg ); inputstream workbookxml = r.getworkbookdata(); ctworkbook ctworkbook = ctworkbook.factory.parse(workbookxml); boolean isdate1904 = ctworkbook.getworkbookpr().getdate1904();

code described in edit section compiles, return null ctworkbookpr in poi 3.9 code below parses workbook prefix:

opcpackage pkg = opcpackage.open(filename); xssfreader r = new xssfreader( pkg ); inputstream workbookxml = r.getworkbookdata(); workbookdocument doc = workbookdocument.factory.parse(workbookxml); ctworkbook wb = doc.getworkbook(); ctworkbookpr prefix = wb.getworkbookpr(); boolean isdate1904 = prefix.getdate1904(); pkg.close();

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
