returning a multidimensional array with explicit return type in c++ -


i have class has member defined as:

float u[2][2];

now have accessor function , return reference array. so, have like:

const float & [2][2] mat() const {     return u; }

is there way return using kind o syntax rather pointer syntax (i think makes things more explicit).

it's awkward, but:

const float (&mat() const)[2][2] {     return u; }

using typedef or decltype might better, eg:

const decltype(u) &mat() const { return u; }

or:

using mat22 = float[2][2]; const mat22 &mat() const { return u; }

(this latter 1 suggested daniel h. in comments).

or, in c++14, just:

const auto &mat() const { return u; }

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
