xcode - LLDB Type Summary with properties (NSManagedObject) -

-

after viewing wwdc2013 lldb debug session, want add custom type formatter 1 nsmanagedobject subclasses. can typing in debugger

type summary -add myclass --summary-string "${var._name}"

this works on variables, not on methods, hence properties. i've tried using python script via valobj.getchildmemberwithname without success.

how can display property on nsmanagedobject subclass on lldb ?

more info: http://lldb.llvm.org/varformats.html

long story short, realized ${var.foo} syntax works ivars. not methods. not properties (which methods, give or take syntactic sugar).

i have been thinking syntax run expressions in string summary format. ${expr:[$var selector]} or ${expr:3+$var}

lacking that, workaround go python, , use sbframe.evaluateexpression command. there examples of python formatters in lldb source code, , on website can use starting point.

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.
