java - Jackson @JsonManagedReference on collection (one to many) -

-

i have following 2 classes.

school has many testtakers

@entity @table(name = "school") @jsonidentityinfo(generator = objectidgenerators.propertygenerator.class, property = "id") public class school extends basemodel {      @column(name = "name")     private string name;     @onetomany(mappedby = "school")     //    @jsonmanagedreference <<<<< if not commented out, error     private set<testtaker> testtakers; //getter setters }  // testtaker.java @entity @table(name = "test_taker") @jsonidentityinfo(generator = objectidgenerators.propertygenerator.class, property = "id") public class testtaker extends basemodel {     @column(name = "first_name")     private string firstname;      @column(name = "last_name")     private string lastname;      @manytoone     @joincolumn(name = "school_id")     @jsonbackreference("school_testtaker")     private school school; //getters setters }

can explain why @jsonmanagedreference cannot annotated on collection? error saying jackson cannot handle managed/back reference. how @jsonmanagedreference work @jsonbackreference in common db relationships one-to-one, one-to-many, many-to-one

i have read documentation, still don't quite understand jackson trying achieve

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.
