how can define method returns list[+anyref]? tried: def a[t <: anyref](): list[t] = list[anyref]() but reason not compile. edit : according wong should use def a[t <: anyref](): list[t] = list[t]() but there way able return subtype of anyref, example def a[t <: anyref](): list[t] = if (value) list[t]() else list[option[string]]() here option[string] descendant of anyref, compiler not accept it so main question if can declare method covariant return type list[+anyref] let's make couple observations , experiment few ways of letting compiler decide on return type: 1) notice statement if (value) list[t]() else list[option[string]]() returns 2 different specific types if statement must return same type , else clauses. when statement returns value, compiler need infer general type 2 clauses bring in consistent constraint. 2) notice type variable t dependent on exact type pass in when call a() , example a[scala.io.source]() . in method decla...

i have question regarding jsf navigation, if want simple page navigation need use redirect method defined in faces-config.xml? for instance have page 1 , user clicks rows in datatable value, navigates page 2 , process , come page 1. i have read in thread here . redirect happens recreate request scope bean. could 1 provide insight this? other options available page page navigation. i using jsf 1.1 appreciate help. regards depends on data wish pass between pages: if data complicated , interconnected ("a wizard scenario") - use faces-config.xml, let pass complex objects between pages; if data can presented simple strings (like "a detail page product_id = 145"), use plain links (like /product.jsf?product_id=145) , inject beans request params using faces-config.xml , managed properties (like: #{param.product_id}). since stuck on using jsf 1.1 (i suspect balusc hard pressed it) - must strive simplicity everywhere else.

how can run services in background of battery manager android application? how display or receive notification when battery low or when criteria met? for example, alarm, when current time equals alarm time alarm rings. you have 3 options: you create long running service. spawns off thread checks things mentioned periodically. wouldn't advise tho, these services tend killed on long run os. also, you'd have use wake locks prevent system put cpu on idle when phone goes idle after minutes of inactivity - stopping service. check out available system events can register broadcast receivers. if find suitable ones (i think there's 1 indicating low battery levels), write receivers them. use timing service register intents fired off on regular intervals. these intents start service (a short running one) thing.

in oracle, appropriate data type or technique representing network addresses, addresses may ipv4 or ipv6? background: i'm converting table recording network activity, built using postgresql inet data type hold both v4 , v6 addresses in same table. no row contains both v4 , v6 addresses, however. (that is, record either machine's v4 stack, or machine's v6 stack.) in oracle, appropriate data type or technique representing network addresses, addresses may ipv4 or ipv6 there 2 approaches : storing only. storing conventional representation for storing only. ipv4 address should integer (32bits enough). ip v6, 128 bits, integer (which similar number(38)) do. of course, that's storing. approach takes view representation matter application. if 1 take opposite strategy, of storing conventional representation, 1 needs make sure ip v4 , ipv6 addresses have 1 conventional (string) representation. it's well-known ipv4. ipv6, there s...
