Example 1 with RELPSocketChannelHandlerFactory

use of org.apache.nifi.processors.standard.relp.handler.RELPSocketChannelHandlerFactory in project nifi by apache.

the class ListenRELP method createDispatcher.

@Override
protected ChannelDispatcher createDispatcher(final ProcessContext context, final BlockingQueue<RELPEvent> events) throws IOException {
    final EventFactory<RELPEvent> eventFactory = new RELPEventFactory();
    final ChannelHandlerFactory<RELPEvent, AsyncChannelDispatcher> handlerFactory = new RELPSocketChannelHandlerFactory<>();
    final int maxConnections = context.getProperty(MAX_CONNECTIONS).asInteger();
    final int bufferSize = context.getProperty(RECV_BUFFER_SIZE).asDataSize(DataUnit.B).intValue();
    final Charset charSet = Charset.forName(context.getProperty(CHARSET).getValue());
    // initialize the buffer pool based on max number of connections and the buffer size
    final BlockingQueue<ByteBuffer> bufferPool = createBufferPool(maxConnections, bufferSize);
    // if an SSLContextService was provided then create an SSLContext to pass down to the dispatcher
    SSLContext sslContext = null;
    SslContextFactory.ClientAuth clientAuth = null;
    final SSLContextService sslContextService = context.getProperty(SSL_CONTEXT_SERVICE).asControllerService(SSLContextService.class);
    if (sslContextService != null) {
        final String clientAuthValue = context.getProperty(CLIENT_AUTH).getValue();
        sslContext = sslContextService.createSSLContext(SSLContextService.ClientAuth.valueOf(clientAuthValue));
        clientAuth = SslContextFactory.ClientAuth.valueOf(clientAuthValue);
    }
    // if we decide to support SSL then get the context and pass it in here
    return new SocketChannelDispatcher<>(eventFactory, handlerFactory, bufferPool, events, getLogger(), maxConnections, sslContext, clientAuth, charSet);
