Example 5 with HttpRequestMethod

use of io.servicetalk.http.api.HttpRequestMethod in project servicetalk by apple.

the class HttpResponseEncoder method sanitizeHeadersBeforeEncode.

@Override
protected void sanitizeHeadersBeforeEncode(HttpResponseMetaData msg, boolean isAlwaysEmpty) {
    // This method has side effects on the methodQueue for the following reasons:
    // - createMessage will not necessarily fire a message up the pipeline.
    // - the trigger points on the queue are currently symmetric for the request/response decoder and
    // request/response encoder. We may use header information on the response decoder side, and the queue
    // interaction is conditional (1xx responses don't touch the queue).
    // - unit tests exist which verify these side effects occur, so if behavior of the internal classes changes the
    // unit test should catch it.
    // - this is the rough equivalent of what is done in Netty in terms of sequencing. Instead of trying to
    // iterate a decoded list it makes some assumptions about the base class ordering of events.
    HttpRequestMethod method = methodQueue.poll();
    HttpHeaders headers = msg.headers();
    if (isAlwaysEmpty) {
        final HttpResponseStatus status = msg.status();
