Examples with Buffer io.vertx.core.buffer.Buffer used on opensource projects

Example 51 with Buffer

use of io.vertx.core.buffer.Buffer in project vert.x by eclipse.

the class ClientConnection method handleResponseEnd.

void handleResponseEnd(LastHttpContent trailer) {
    if (metrics.isEnabled()) {
        HttpClientRequestBase req = currentResponse.request();

        if (HttpHeaders.Values.CLOSE.equalsIgnoreCase(responseConnectionHeader) || HttpHeaders.Values.CLOSE.equalsIgnoreCase(requestConnectionHeader)) {
            // In all cases, if we have a close connection option then we SHOULD NOT treat the connection as persistent
            close = true;
        } else if (protocolVersion == io.vertx.core.http.HttpVersion.HTTP_1_0 && !HttpHeaders.Values.KEEP_ALIVE.equalsIgnoreCase(responseConnectionHeader)) {
            // In the HTTP/1.0 case both request/response need a keep-alive connection header the connection to be persistent
            // currently Vertx forces the Connection header if keepalive is enabled for 1.0
            close = true;
        }

public void pump2(Vertx vertx) {
    NetServer server = vertx.createNetServer(new NetServerOptions().setPort(1234).setHost("localhost"));
    server.connectHandler(sock -> {
        sock.handler(buffer -> {

the class ConnectionHolder method writeMessage.

// TODO optimise this (contention on monitor)
synchronized void writeMessage(ClusteredMessage message) {
    if (connected) {
        Buffer data = message.encodeToWire();
        metrics.messageWritten(message.address(), data.length());

Example 54 with Buffer

use of io.vertx.core.buffer.Buffer in project vert.x by eclipse.

the class SharedDataExamples method example1.

public void example1(Vertx vertx) {
    SharedData sd = vertx.sharedData();
    LocalMap<String, String> map1 = sd.getLocalMap("mymap1");
    // Strings are immutable so no need to copy
    map1.put("foo", "bar");
    LocalMap<String, Buffer> map2 = sd.getLocalMap("mymap2");
    // This buffer will be copied before adding to map
    map2.put("eek", Buffer.buffer().appendInt(123));
    // Then... in another part of your application:
    map1 = sd.getLocalMap("mymap1");
    String val = map1.get("foo");
    map2 = sd.getLocalMap("mymap2");
    Buffer buff = map2.get("eek");
