android programming can httpurlconnection be used in webroot -


i wondering can connect android webroot of project in order communicate mysql or can done web url? instance examples have seen off android communicating mysql using url such 

  url url = new url("www.mysite.net/connect.php");                 httpurlconnection urlc = (httpurlconnection) url.openconnection();

but possible this

      url url = new url("mysite/webroot/connect.php");                 httpurlconnection urlc = (httpurlconnection) url.openconnection();

the reason being not have website , examples of connecting databases use valid url.

httpurlconnection it's name implies:

  • connect url, gives ip address connect to
  • use http protocol communicate server

first of all, think you're trying achieve local database, database resides on android phone itself. in case, httpurlconnection unrelated :)

there plenty of tutorials , references connecting local database, should start here: http://developer.android.com/training/basics/data-storage/databases.html

however, if trying connect remote database (a database living within internet, , not phone), that's complex beast wishing tackle :p , also unrelated httpurlconnection, mysql has it's own communication protocol not http. recommended access database via restful api, translates website.

good luck

c++ - Why doesn't unordered_set provide an array access operator -

i'm curious why stl container unordered_set , has constant time complexity random access on average, not provide method accessing elements distance first element in container. example: t& unordered_set::operator[](size_t index) { return *(begin() + index); } accessing element "by distance" implies there meaningful way measure distance. trouble std::unordered_set is is, well, unordered . hence, there no meaningful way of explaining "some distance beginning" in non-arbitrary way. if want access distance, copy data vector: std::vector tmp(unordered.begin(), unordered.end());
