regex - emacs greedy search-backward-regexp -

how make backward regexp search greedy in emacs?

for example, have abc 163439 abc in buffer, , run m-x search-backward-regexp following regexp: 163439\|3. regexp allways find '3' in buffer, newer whole long number. because, when starts search, meet '3' firstly. in second try, start position of '3', inside number, , omit it.

how can find longest , closest match?

so mean, when meet '3', want check if matched part isn't part of bigger match.

i don't think can want.

emacs search-backward-regexp searches closest instance matches regular exprssion. not greediness (greediness in regular expressions matching many characters possible when there kleene star operator -- or syntactic variants ? or +).

in example, emacs finds first instance matches regular expression.

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.
