c++ - How works - Pointer / Unique_ptr without new -

foo.h #include <iostream> #include <memory> class bar { public: bar() {}; ~bar() {}; void print() { std::cout << "hello"; } }; class foo { public: foo(); ~foo(); void use() { pteste->print(); } private: std::unique_ptr<bar> pteste; }; #endif main.cpp #include <memory> #include "foo.h" int main(int argc, char *argv[]) { foo s; s.use(); return 0; } why , how works "normally"? thanks edit: understand incomplete types, happens when can use unique_ptr without using new , why works edit2: organized code better question short answer: doesn't work. this reference says default constructor of std::unique_ptr creates empty unique pointer, meaning has no associated object. the reason why code prints hello because statement std::cout << "hello"; doesn't need of bar . static method. maybe compiler inlines f

python - OpenERP - onchange method for fields in different page of view? -

-
it seems onchange method works on current visible fields. if use fill other fields in other pages of view, not anything. example have view many pages. information needs filled in first page, fields filled correctly. there 1 field need fill in other page, when choose partner_id in page. example in view this: ... <page string="page1"> <field name=partner_id on_change="onchange_partner(partner_id)" <field name="field1"/> <field name="field2"/> </page> <page string="page2"> <field name="field3"/> </page> ... field1 , field2 filled. how fill field3 or impossible, because system not save database using onchange method? my onchange method looks this: def onchange_partner(self, cr, uid, ids, partner_id, context=none): res = {} if partner_id: obj = self.pool.get('res.partner').browse(cr, uid, partner_id) res['field1'] = obj.field1 res[

who could explain more about the compare function in priority queue C++ -

we define operator < people seem use class define operator ()? how work. i have learned generic thing in c before, @ time, use pointer function. what difference? basically, want code contain least amount of surprises. let's have std::priority_queue<t> pq class t . t class natural ordering exists? if so, define operator < it. want pq prioritised based on ordering? if so, let use operator < , you're done. however, quite often, t class no intrinsic notion of ordering. imagine class employee storing name , startingdate , salary . there no universal ordering - given 2 employees, it's not clear 1 < other. at same time, may want std::priority_queue<employee> based on earns most. or least. or who's company longest. therefore, you'll use specific comparators these. in way, priority queue comparator , operator < independent concepts. if have naturally orderable class, give operator < . if want priority queue

java - Preventing split packets over TCP -

-
i writing program transfers files on network using tcp sockets. now noticed when send packet in size example 1024 bytes, them split on other side. by "split" mean packets if part of whole packet. i tried reduce packet size , algorithm worked, when packet size immensely small (about 30 bytes per packet) file transferred slowly. is there can in order prevent splitting? solved:i switched connection on udp , since udp packet bounded worked there not such thing in tcp. tcp stream, write @ other end. not mean way written; tcp may break or group packets in order jobs possible. can send 8 mega bytes packet in 1 write , tcp can break down 10, 100 or 1000 packets, need know @ other end 8 mega bytes no more no less. in order file transfer need tell receiver how many bytes going send. receiver may read in 1 chunk or in 100 chunks must keep track of data reads , how many bytes read.

doesn't call method onstart after screen locked android 2.3, after unlocking called resume method. on andoid 4.1.2 (jelly brain) works fine. can fixed ? or must move logic in method onresume/onpause ? the methods onstart , onstop bound visible lifetime of activity. if lockscreen not hide activity, these methods not called @ all. if have logic depending on different states use foreground lifetime methods onresume , onpause or observer techniques broadcastreceiver. also remember, prior android honeycomb application killable after onpause , onstop might not called @ all.
