Re: [akka-user] [Stream] Connecting arbitrary number of graphs with materialized values

Yeah, that's what I ended up doing. It's just a little less general than chaining all the values together and then combining them. Thanks, Tal On Monday, March 7, 2016 at 8:46:40 AM UTC+2, hbf wrote: > > Can you do it recursively? Write method that takes two and combines their > materialized

Re: [akka-user] [Stream] Connecting arbitrary number of graphs with materialized values

Can you do it recursively? Write method that takes two and combines their materialized values. Then recurse to do *n*. Hbf. On Friday, 26 February 2016 05:02:34 UTC-8, Tal Pressman wrote: > > This isn't actually a matter of size - I don't expect that I'll have too > many sinks, I just don't

Re: [akka-user] [Stream] Connecting arbitrary number of graphs with materialized values

This isn't actually a matter of size - I don't expect that I'll have too many sinks, I just don't know how many I'll have ahead of time. Tal On Friday, February 26, 2016 at 2:49:16 PM UTC+2, drewhk wrote: > > > > On Fri, Feb 26, 2016 at 1:45 PM, Tal Pressman > wrote: > >>

Re: [akka-user] [Stream] Connecting arbitrary number of graphs with materialized values

Hi, So in my case all the sinks return a Future (well, CompletionStage) and I want to sequence them. I understand the HLists might be a little too complicated (and I'm not sure if it can be used from Java...) but I still think something that works on a Seq of the least common ancestor could be

Re: [akka-user] [Stream] Connecting arbitrary number of graphs with materialized values

Hi Tal, The issue why you can't convert in the GraphDSL an arbitrary number of materialized values is because that would need HLists (lists if heterogeneous types, a generalization of tuples). What is exactly what you want to achieve? -Endre On Thu, Feb 25, 2016 at 3:50 PM, Tal Pressman

[akka-user] [Stream] Connecting arbitrary number of graphs with materialized values

Hi, I find myself needing a way to send messages to several sinks, while aggregating their materialized values. Trying to use the GraphDSL, I can either: - Pass a static number of graphs to GraphDSL.create and use their materialized values, or - Call builder.add for each graph, but
