Class JsonTextSequences

java.lang.Object

com.linecorp.armeria.server.streaming.JsonTextSequences

public final class JsonTextSequences
extends Object

A utility class which helps to create a JavaScript Object Notation (JSON) Text Sequences from a content Publisher or Stream.

A user simply creates a streaming HttpResponse which emits JSON Text Sequences, e.g.

 ObjectMapper mapper = new ObjectMapper().enable(SerializationFeature.INDENT_OUTPUT);
 Server server =
     Server.builder()
           // Emit JSON Text Sequences with a default ObjectMapper.
           .service("/seq1",
                    (ctx, req) -> JsonTextSequences.fromPublisher(Flux.just("foo", "bar")))
           // Emit JSON Text Sequences with the ObjectMapper
           // configured to use the default pretty printer.
           .service("/seq2",
                    (ctx, req) -> JsonTextSequences.fromPublisher(Flux.just("foo", "bar"), mapper))
           .build();
