Is there a way to add constructors using Groovy 2.0 Extensions -

-

in older (1.x.x) versions of groovy can add constructors using metaclass.constructor 

example.metaclass.constructor << { string arg0 -> new example(arg0, "") }

is there way register constructors using new groovy 2.0 extension modules?

this seems work:

define extension class normal groovy 2 , add constructors in static initialiser

public class examplehelper {     static {         example.metaclass.constructor << { string arg0 -> new example(arg0, "") }     } }

not know of...

you add static factory method example class ie:

class exampleextensionstatic {   public static example newinstance( example type, string arg0 ) {     new example( arg0, '' )   } }

then (after adding link class in staticextensionclasses field of org.codehaus.groovy.runtime.extensionmodule file), do:

example.newinstance( 'arg0' )

this worth asking on mailing list see if constructors worth adding module extension system.

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...
