Re: [aerogear-dev] [Aerogear Pipeline] Support for nested endpoints

Hi some comments I believe the method can't be used since you don't know the team for the players so you can't retrieve the pipe directly..right?

getPlayers(Callback<List<Player>> callback) { pipe.get("player").read(callback); } Further my questions is, how is a third (or arbitrary) nested resources are supported? I mean for a url schema like this soccer.org/leagues/{id}/teams/{id}/players/{id} first we access the leagues: --- getLeagues(Callback<List<Leagues>> callback) { pipe.get("leagues").read(callback); } --- then the teams for this league: --- getTeamsOnLeaque(Leaque league, Callback<List<Team>> callback) { pipe.junction("league","team").read(leaque, callback); } --- ..and then we access the "Players" for a "Team": --- getPlayersOnTeam(Team team, Callback<List<Player>> callback) { pipe.junction("team","player").read(team, callback); } --- But where is the "League" information to fill the "/leagues/{id}..." path?

Unless you mean something like: --- getPlayersOnTeam(Leaque league, Team team, Callback<List<Player>> callback) { pipe.junction("league", "team","player").read(league, team, callback); }

--- probably I am missing sth..

It isn't a Pipe though, but perhaps that could be changed to look more like Christos's previous example. At the very least I like the words "junction" or "join" more than "of" ----- Original Message ----- | From: "Christos Vasilakis" <cvasilak(a)gmail.com&gt; | To: "AeroGear Developer Mailing List" <aerogear-dev(a)lists.jboss.org&gt; | Sent: Wednesday, April 3, 2013 3:03:02 AM | Subject: Re: [aerogear-dev] [Aerogear Pipeline] Support for nested endpoints | | | On Apr 2, 2013, at 4:03 PM, Matthias Wessendorf < matzew(a)apache.org > wrote: | | | | | Two thoughts.... | | 1) the 'original' leaguesPipe has no clue about the subpipes, right ? | 2) should a pipe offer a 'getter' for all it's sub pipes ? | | | Just a thought is instead of using Pipe, to continue using Pipeline adding an | extra parameter " of" for specifying the parent : E.g.: | | ….. | id<AGPipe> leaguesPipe = [pipeline pipe@"leagues"]; | | id<AGPipe> allTeamsInSeattlePipe = [pipeline subPipe@"teams" of :leaguesPipe | for:@"seattle"] | | id<AGPipe> allPlayersInTrebuchetPipe = [pipeline subPipe:@"players" of: | allTeamsInSeattlePipe for:@"trebuchet"]; | ….. | | | Wdyt? | | | | | | | | -M | | | | | | Thanks, | Christos | | | | | | | | | | | | | | | soccer.org/leagues/seattle/teams/trebuchet/players/foo - > | [[pipeline pipe:@"players" pathParams:@[@"seattle", @"trebuchet"]] read | :@"foo"] .. | ----- | | | Wdyt? | | Thanks | Christos | | On Mar 18, 2013, at 1:12 PM, Sebastien Blanc < scm.blanc(a)gmail.com > wrote: | | | | Well, that would not be possible, for that you will have to create a "child" | pipe.
