how set handler receive messages in pyfirmata arduino uno?

i have following python code:

from logic.moduleclass import module events.eventdispatcherclass import event pyfirmata import arduino, util import pyfirmata  class comm(module):     """     handles communication between python , arduino     attachto: ""     """      name = "communicator"      def __init__(self, port):         super(comm,self).__init__(comm.name)         self.board = arduino(port)         # start iterator thread serial buffer doesn't overflow         = util.iterator(self.board)         it.start()          self.board.add_cmd_handler(pyfirmata.pyfirmata.string_data, self._messagehandler)      def _messagehandler(self, *args, **kwargs):         print args      def update(self):         super(comm,self).update()      def writedata(self,data):         #print data         self.board.send_sysex(pyfirmata.pyfirmata.string_data,data)      def dispose(self):         super(comm,self).dispose()         try:             self.board.exit()         except attributeerror:             print "exit() raised attributeerror unexpectedly!"+self.tostring()

on arduino, i'm sending string this:

firmata.sendstring("test");

i added _messagehandler(self, *args, **kwargs) , i'm getting collection of assume character codes. i'm new python , i'm not sure how can original string send arduino

i have found solution:

to convert string send arduino pyfirmata use following code in python:

def _messagehandler(self, *args, **kwargs):     print util.two_byte_iter_to_str(args)

that should return string you're expecting. ftw!

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.
