Serialize Your Domain Objects with IPdxSerializer

For domain objects that you cannot or do not want to modify, use the IPdxSerializer class to serialize and deserialize the object’s fields.

You use one IPdxSerializer implementation for the entire cache, programming it for all of the domain objects that you handle in this way. This way you do not have to implement the IPdxSerializable interface for each domain class.

With IPdxSerializer, you leave your domain object as-is and handle the serialization and deserialization in the separate serializer. You register the serializer in your cache PDX configuration. Then program the serializer to handle all of the domain objects you need.

If you write your own IPdxSerializer and you also use the ReflectionBasedAutoSerializer, then the IPdxSerializer needs to own the ReflectionBasedAutoSerializer and delegate to it. A cache can only have a single IPdxSerializer instance.

Note: The IPdxSerializer toData and fromData methods differ from those for IPdxSerializable. They have different parameters and results.

To register an IPdxSerializer, you can use the following code. Note that you can only register the IPdxSerializer in the application code. It cannot be configured declaratively in cache.xml.


using Apache.Geode.Client;
// Register a PdxSerializer to serialize
// domain objects using PDX serialization

Serializable.RegisterPdxSerializer(new MyPdxSerializer());
