Example 6 with Serialization

use of org.apache.dubbo.common.serialize.Serialization in project dubbo by alibaba.

the class ExchangeCodec method encodeRequest.

protected void encodeRequest(Channel channel, ChannelBuffer buffer, Request req) throws IOException {
    Serialization serialization = getSerialization(channel, req);
    // header.
    byte[] header = new byte[HEADER_LENGTH];
    // set magic number.
