Example 1 with GenericType

use of io.helidon.common.GenericType in project helidon by oracle.

the class JacksonBodyStreamWriter method write.

@Override
public Multi<DataChunk> write(Flow.Publisher<?> publisher, GenericType<?> type, MessageBodyWriterContext context) {
    MediaType contentType = context.findAccepted(MediaType.JSON_PREDICATE, MediaType.APPLICATION_JSON);
    context.contentType(contentType);
    AtomicBoolean first = new AtomicBoolean(true);
    JacksonBodyWriter.ObjectToChunks objectToChunks = new JacksonBodyWriter.ObjectToChunks(objectMapper, context.charset());
    return Multi.create(publisher).flatMap(objectToChunks).flatMap(it -> {
        if (first.getAndSet(false)) {
            // first record, do not prepend a comma
            return Multi.just(DataChunk.create(ARRAY_JSON_BEGIN_BYTES), it);
        } else {
            // any subsequent record starts with a comma
            return Multi.just(DataChunk.create(COMMA_BYTES), it);
        }
    }).onCompleteResume(DataChunk.create(ARRAY_JSON_END_BYTES));
}

Example 2 with GenericType

use of io.helidon.common.GenericType in project helidon by oracle.

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    WRITER.write(publisher, type, CONTEXT).map(DataChunk::bytes).forEach(it -> {
        try {
            baos.write(it);
        } catch (IOException ignored) {

        }
    }).await();
    return JSON_PARSER.createReader(new ByteArrayInputStream(baos.toByteArray())).readArray();
}

Example 3 with GenericType

use of io.helidon.common.GenericType in project helidon by oracle.

@Override
public Multi<DataChunk> write(Publisher<? extends JsonStructure> publisher, GenericType<? extends JsonStructure> type, MessageBodyWriterContext context) {
    MediaType contentType = context.findAccepted(MediaType.JSON_PREDICATE, MediaType.APPLICATION_JSON);
    context.contentType(contentType);
    // we do not have join operator
    AtomicBoolean first = new AtomicBoolean(true);
    JsonStructureToChunks jsonToChunks = new JsonStructureToChunks(true, jsonWriterFactory, context.charset());
    return Multi.create(publisher).map(jsonToChunks).flatMap(it -> {

            return Multi.just(DataChunk.create(ARRAY_JSON_BEGIN_BYTES), it);
        } else {
            // any subsequent record starts with a comma
            return Multi.just(DataChunk.create(COMMA_BYTES), it);
        }
    }).onCompleteResume(DataChunk.create(ARRAY_JSON_END_BYTES));
}

Example 4 with GenericType

use of io.helidon.common.GenericType in project helidon by oracle.

the class JsonbNdBodyStreamWriter method write.

@Override
public Multi<DataChunk> write(Flow.Publisher<?> publisher, GenericType<?> type, MessageBodyWriterContext context) {
    MediaType contentType = MediaType.APPLICATION_X_NDJSON;
    context.contentType(contentType);
    AtomicBoolean first = new AtomicBoolean(true);
    return Multi.create(publisher).map(object -> DataChunk.create(jsonb.toJson(object).getBytes(StandardCharsets.UTF_8))).flatMap(dataChunk -> {
        if (first.getAndSet(false)) {

Example 5 with GenericType

use of io.helidon.common.GenericType in project helidon by oracle.

the class FormParamsBodyReader method read.

@Override
@SuppressWarnings("unchecked")
public <U extends FormParams> Single<U> read(Flow.Publisher<DataChunk> publisher, GenericType<U> type, MessageBodyReaderContext context) {
    MediaType mediaType = context.contentType().orElseThrow();
    Charset charset = mediaType.charset().map(Charset::forName).orElse(StandardCharsets.UTF_8);
    Function<String, String> decoder = decoder(mediaType, charset);
    return (Single<U>) ContentReaders.readString(publisher, charset).map(formStr -> create(formStr, mediaType, decoder));
