apache spark - Parse complex XML file to get object and its fields -

-

is there way parse complex xml file child element object fields/members accessible in 1 read?

i'm working on code passed me uses dom4j , developer did read each node. object fields , members, read file 4 or 5 times each one. build object have make these calls? takes 15 secs run.

maybe dom4j can more 1 element in 1 read of file?

is jaxb more that, giving reference object , fields in 1 read?

is spark or hadoop better/faster performance wise?

you see i'm looking read xml file , extract element child elements, etc build objects in 1 read.

let me know work best!

since dom4j reads entire file , builds object graph in memory, there shouldn't need "read" file more once.

on other hand, if have schema type of document processing, jaxb better alternative.

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.
