.net - Regex commas out of expression -

-

i attempting regex replace commas in-between quotations in string. can't seem match them in non-greedy fashion won't regex entire line. text , regex i'm trying below. regex i'm trying, picking commas in-between each element. ex "remove,comma","nocomma" yields "remove,comma" , "," match. also, picking matches "nocomma"," "nocomma","nocomma".

i working on matching first, narrowing down replacing commas.

using .net 4.0

text before regex

"remove,comma","remove,comma","nocomma","remove,comma","remove,all,commas,here,too","also,remove,commas"

text want after before regex

"removecomma","removecomma","nocomma","removecomma","removeallcommasheretoo","alsoremovecommas"

regex

\".*?(,).*?\" 

regex.replace(input,@",(?!([^""]*""[^""]*"")*[^""]*$)","");

the above regex replace , if odd number of " ahead..this because , within "" have odd number of " ahead.

[^"]* match 0 many characters not "

$ depicts end of string

(?!) negative lookahead

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
