 * A base class for custom serialization. User can register custom serializer like following:

 * 
 *     final SerializerConfig serializerConfig = new SerializerConfig();
 *     serializerConfig.setImplementation(new StreamSerializer() {
 *          public int getTypeId() {
 *
 *          }

 *          public Person read(ObjectDataInput in) throws IOException {
 *
 *          });
 *
 *     serializerConfig.setTypeClass(Person.class);
 *     config.getSerializationConfig().addSerializerConfig(serializerConfig);
 *
 * 
 * 
 * There is another class with byte arrays can be used instead ıf this interface
 * see {@link com.hazelcast.nio.serialization.ByteArraySerializer}.
 * 

 * C++ and C# clients also have compatible methods so that with custom serialization client can also be used
 * 
 * Note that read and write methods should be compatible
