Examples with IOService com.hazelcast.nio.IOService used on opensource projects

Example 1 with IOService

use of com.hazelcast.nio.IOService in project hazelcast by hazelcast.

the class SocketWriterInitializerImpl method initHandler.

private void initHandler(TcpIpConnection connection, SocketWriter writer, String protocol) {
    WriteHandler handler;
    if (CLUSTER.equals(protocol)) {
        IOService ioService = connection.getConnectionManager().getIoService();
        handler = ioService.createWriteHandler(connection);
    } else if (CLIENT_BINARY_NEW.equals(protocol)) {
        handler = new ClientWriteHandler();
    } else {
        handler = new TextWriteHandler(connection);
    }
    writer.initWriteHandler(handler);
}

Example 2 with IOService

use of com.hazelcast.nio.IOService in project hazelcast by hazelcast.

the class SocketReaderInitializerImpl method init.

@Override
public void init(TcpIpConnection connection, SocketReader reader) throws IOException {
    TcpIpConnectionManager connectionManager = connection.getConnectionManager();
    IOService ioService = connectionManager.getIoService();
    ByteBuffer protocolBuffer = reader.getProtocolBuffer();
    SocketChannelWrapper socketChannel = reader.getSocketChannel();
    int readBytes = socketChannel.read(protocolBuffer);
    if (readBytes == -1) {
        throw new EOFException("Could not read protocol type!");
    }
    if (readBytes == 0 && connectionManager.isSSLEnabled()) {
        // when using SSL, we can read 0 bytes since data read from socket can be handshake frames.
        return;
    }
    if (protocolBuffer.hasRemaining()) {
        // we have not yet received all protocol bytes
        return;
    }
    ReadHandler readHandler;
    String protocol = bytesToString(protocolBuffer.array());
    SocketWriter socketWriter = connection.getSocketWriter();
    if (CLUSTER.equals(protocol)) {
        initInputBuffer(connection, reader, ioService.getSocketReceiveBufferSize());
        connection.setType(MEMBER);
        socketWriter.setProtocol(CLUSTER);
        readHandler = ioService.createReadHandler(connection);
    } else if (CLIENT_BINARY_NEW.equals(protocol)) {
        initInputBuffer(connection, reader, ioService.getSocketClientReceiveBufferSize());
        socketWriter.setProtocol(CLIENT_BINARY_NEW);
        readHandler = new ClientReadHandler(reader.getNormalFramesReadCounter(), connection, ioService);
    } else {
        ByteBuffer inputBuffer = initInputBuffer(connection, reader, ioService.getSocketReceiveBufferSize());
        socketWriter.setProtocol(TEXT);
        inputBuffer.put(protocolBuffer.array());
        readHandler = new TextReadHandler(connection);
        connectionManager.incrementTextConnections();
    }
    if (readHandler == null) {
        throw new IOException("Could not initialize ReadHandler!");
    }
    reader.initReadHandler(readHandler);
}

Example 3 with IOService

use of com.hazelcast.nio.IOService in project hazelcast by hazelcast.

the class SocketWriterInitializerImpl method initOutputBuffer.

private void initOutputBuffer(TcpIpConnection connection, SocketWriter writer, String protocol) {
    IOService ioService = connection.getConnectionManager().getIoService();
    int sizeKb = CLUSTER.equals(protocol) ? ioService.getSocketSendBufferSize() : ioService.getSocketClientSendBufferSize();
    int size = KILO_BYTE * sizeKb;
    ByteBuffer outputBuffer = newByteBuffer(size, ioService.isSocketBufferDirect());
    if (CLUSTER.equals(protocol)) {
        outputBuffer.put(stringToBytes(CLUSTER));
    }
    writer.initOutputBuffer(outputBuffer);
    try {
        connection.setSendBufferSize(size);
    } catch (SocketException e) {
        logger.finest("Failed to adjust TCP send buffer of " + connection + " to " + size + " B.", e);
    }
