c++ - What kind of exception is thrown by boost::ifind_first? -


i've found boost documentation frustrating read , despite best effort, cannot determine kind of exception may thrown in call boost::ifind_first. documentation notes:

this function provides strong exception-safety guarantee

however there no notes on type of exception may thrown. primary question how determine exception may thrown ifind_first?

it tough answer since, stated, documentation use kick in butt. being said when boost says:

this function provides strong exception-safety guarantee

they refering exception-safety in generic components states:

the strong guarantee provides full “commit-or-rollback” semantics. in case of c++ standard containers, means, example, if exception thrown iterators remain valid. know container has same elements before exception thrown. transaction has no effects if fails has obvious benefits: program state simple , predictable in case of exception. in c++ standard library, of operations on node-based containers list, set, multiset, map, , multimap provide strong guarantee.4).

i using boost::exception class catch general exception, feed data should break , figure out throws there.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

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...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
