activepivot - How to use Relational Stores with a position based data file? -

-

i have different data files mapped on relational stores. have formatter contains separators used different data files (most of them csv). here example of how looks like:

dqki 435741198746445 45879645422727jhufhglobal collateral services aggregator v9

the rule read file following: index 0 3, it's code name, index 8 11, it's pid, index 11 20, it's account number, , on...

how specify such rule in activepivot relational stores?

the relational-store of activepivot ships high performance, multithreaded csv-source parse files , load them data stores. suppose that's hope use fixed-length field file.

but not supported in current version of relational store (1.5.x).

  • you pre-process file small script add separator character @ end of each of fields. entire csv source can reused immediately.

  • you write own data source defines fields offset in text line. if can reuse of fast field parsers available in csv source project (they work on char sequences):

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
