Example 1 with LimitedDataBufferList

use of org.springframework.core.io.buffer.LimitedDataBufferList in project spring-framework by spring-projects.

the class StringDecoder method decode.

@Override

    byte[][] delimiterBytes = getDelimiterBytes(mimeType);
    LimitedDataBufferList chunks = new LimitedDataBufferList(getMaxInMemorySize());
    DataBufferUtils.Matcher matcher = DataBufferUtils.matcher(delimiterBytes);
    return Flux.from(input).concatMapIterable(buffer -> processDataBuffer(buffer, matcher, chunks)).concatWith(Mono.defer(() -> {
        if (chunks.isEmpty()) {
            return Mono.empty();
        }
        DataBuffer lastBuffer = chunks.get(0).factory().join(chunks);
        chunks.clear();
        return Mono.just(lastBuffer);
    })).doOnTerminate(chunks::releaseAndClear).doOnDiscard(PooledDataBuffer.class, PooledDataBuffer::release).map(buffer -> decode(buffer, elementType, mimeType, hints));
