c++ - Testing for valid arguments in the internal interfaces that client can't see -


it's practice test arguments in function before function real processing begins.

but true internal functions , interfaces? boss(my tech lead) told me don't need check things in internal interfaces, because front end filtering them out.

so true, suppose protocol, , when protocol have many layers, , think protocol our internal protocol okay ignore checks because use protocol internally?

but true internal functions , interfaces ? boss( tech lead ) told me don't need check things in internal interfaces, because front end filtering them out.

your boss right insofar should frontends code responsibility , makes no sense checks again , again (which hurts performance).

probably best practice use assert() parameter checks. don't have rely on frontends functionality during debugging , testing phase, checks removed production code.

one thing dislike assert() approach is, it's debugging unfriendly.
it's way easier catch exception , check call stack see culprit was. maybe better idea regarding write own kind of assert() macro, doesn't call abort(), throws appropriate exception. same original assert() erased production code.

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...
