Example 26 with DataWrapper

use of org.webpieces.data.api.DataWrapper in project webpieces by deanhiller.

the class MockHttp2Channel method write.

public void write(Http2Msg msg) {
    if (listener == null)
        throw new IllegalStateException("Not connected so we cannot write back");
    DataWrapper data = parser.marshal(marshalState, msg);
    byte[] bytes = data.createByteArray();
    if (bytes.length == 0)
        throw new IllegalArgumentException("how do you marshal to 0 bytes...WTF");
    ByteBuffer buf = ByteBuffer.wrap(bytes);
    listener.incomingData(this, buf);
}

Example 27 with DataWrapper

use of org.webpieces.data.api.DataWrapper in project webpieces by deanhiller.

the class MockHttp2Channel method processData.

@SuppressWarnings("unchecked")
private CompletableFuture<Channel> processData(ByteBuffer b) {
    DataWrapper data = dataGen.wrapByteBuffer(b);
    parser.unmarshal(unmarshalState, data);

Example 28 with DataWrapper

use of org.webpieces.data.api.DataWrapper in project webpieces by deanhiller.

the class Level3ClntOutgoingSyncro method sendInitializationToSocket.

public CompletableFuture<Void> sendInitializationToSocket() {
    //important, this forces the engine to a virtual single thread(each engine/socket has one virtual thread)
    //this makes it very easy not to have bugs AND very easy to test AND for better throughput, you can
    //just connect more sockets
    log.info("sending preface");
    DataWrapper prefaceData = dataGen.wrapByteArray(preface);
    return finalLayer.sendPreface(prefaceData).thenCompose(v -> super.sendSettingsToSocket());
}

Example 29 with DataWrapper

use of org.webpieces.data.api.DataWrapper in project webpieces by deanhiller.

the class Preface method verify.

    DataWrapper data = dataGen.wrapByteBuffer(buffer);
    String content = data.createStringFromUtf8(0, data.getReadableSize());
    if (!"PRI * HTTP/2.0\r\n\r\nSM\r\n\r\n".equals(content))
        throw new IllegalStateException("preface incorrect=" + content);

Example 30 with DataWrapper
