java - (J2me) Stream as a buffer? -

-

here got j2me application , need transmit or save live data output stream.

what happen if use 1 thread write data stream , after writing no ofl bytes other thread bytearray out of save or transmit , reset stream zero..

i.e calling reset on .. equals using stream fixed size buffer..

the constrain here may not able use bytebuffer object purpose

will make stream invalid because first thread still wiring it?

i assume going use java.io.bytearrayoutputstream class, part of cldc 1.0 standard of j2me.

cldc 1.0 not thread safety of bytearrayoutputstream.

but if implementation of bytearrayoutputstream, needed methods seems synchronized:

public synchronized byte tobytearray()[] { ... } public synchronized void reset() { ... } public synchronized void write(byte b[], int off, int len) { ... }

if have access sources of j2me classes. can double check that.

if methods synchronized, should safe use stream plan.

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...
