java - hibernate save and read from DB -

-

i new in java , use hibernate.

i added in code datapoints instances:

datapoint dp = new datapoint(); dp.setdataset(dataset); dp.setstation(station);

i run dataset.getdatapointcount() function has count dp dataset id:

public int getdatapointcount()     {          criteria        crit = database.getsession().createcriteria(datapoint.class);          crit = crit.add(restrictions.eq("dataset", this));         crit.setprojection(projections.rowcount());          integer         result = (integer)crit.uniqueresult();          return result.intvalue();     }

and got 0 datapoints. (when run finished see new datapoints in database).

i added 

 database.getsession().flush();

before getdatapointcount() function , realy return new number (1000 example)

but in end of runing datapoints didnt saved in database!

in addition, if write getdatapointcount() after filush() twice ,i got in first

time right answer(1000) , in second time no right answer (0)

can 1 me?

thanks in advance.

what value of flushmode using ?

a transaction not commited can reason data not saved db.

see hibernate flushmode doc

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
