java - Invoke methods with different arguments in a generic way -

-

im trying write generic code, can invoke methods @ runtime different number & type of arguments. have class & different methods @ disposal reading file, along arguments passed particular method.

so, here's object array contains values of different type -

object[] args = new object[]{"astring", 1, true};

/* based on object java.lang.reflect.method.invoke(object obj, object... args) , have written following method */

//"executingmethod" references method executed, 1 can class.forname("classname").getdeclaredmethods(); , traversing particular method.

executingmethod.invoke(methodclassobject, args); //and doesn't execute because @ runtime doesn't know(can't downcast) param "type".

i don't want pass args[0], args[1], args[2] inside executingmethod.invoke(..), case number of arguments may vary.

any suggestions pls??

here 1 way deal problem:

create following interface

import java.util.arraylist; public interface executableinterface {     void executable(string methodname);     string getexecutablemethod();     void setparameters(arraylist parameters);     arraylist getparameters(); }

now, in class want invokable, make implement methods , pass invokable method using executable , pass parameters using setparameter.

at runtime values , call executable method returns getexecutablemethod. same way parameters.

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...
