Writing byte[] as text to JsonGenerator

[Volkan Yazıcı]

Hello,

I have a byte[] of a text. How can I write (incl. escaping) this to a JsonGenerator. JsonGenerator#writeRawUTF8String(byte[] buffer, int offset, int length) does the job, but misses escaping.

To provide further background, I am trying to serialize a stack trace to text. But while doing so, I am using a pool of byte[] to avoid allocation. That is,

public void resolve(Throwable throwable, JsonGenerator jsonGenerator) throws Exception {
    ByteBufferOutputStream outputStream = outputStreamPool.acquire();
    try (PrintStream printStream = new PrintStream(outputStream, false, "UTF-8")) {
        exception.printStackTrace(printStream);
    }
    ByteBuffer outputStreamBuffer = outputStream.getByteBuffer();
    jsonGenerator.writeRawUTF8String(outputStreamBuffer.array(), 0, outputStreamBuffer.position());
    outputStreamPool.release(outputStream);
}

I will appreciate any tips.

Thanks in advance.

Best.

If you need escaping, you will not really benefit from feeding UTF-8
encoded input source: it will unfortunately need to go back to
character, that is, decoded into Java Strings or `char[]`.
