public interface StreamSerializer<T>
extends Serializer

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 void destroy() {

          }

          public void write(ObjectDataOutput out, Person object) throws IOException {

          }

          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 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

Method Detail

write

void write(ObjectDataOutput out,
           T object)
    throws IOException

This method writes object to ObjectDataOutput

Parameters:

out - ObjectDataOutput stream that object will be written to

object - that will be written to out

Throws:

IOException - in case of failure to write

read

T read(ObjectDataInput in)
throws IOException

Reads object from objectDataInputStream

Parameters:

in - ObjectDataInput stream that object will read from

Returns:

read object

Throws:

IOException - in case of failure to read
