Serializing Data with GemFire PDX Serialization

When you use GemFire PDX serialization with the native client C++ API, you can register a PdxSerializer for the entire cache or implement PDX serialization for each domain object.

You can also set the object preference of the cache to the PdxInstance type, which allows you to access fields of a PDX object without deserializing the entire object.

• Serialize Your Domain Objects with PdxSerializer and PdxWrapper
  For domain objects that you cannot or do not want to modify, use the PdxSerializer and the PdxWrapper classes to serialize and deserialize the object's fields.
• Serialize Using the GemFire PdxSerializable Class
  Domain classes need to inherit the PdxSerializable abstract class to serialize and de-serialize the object. When you write objects using PDX serialization, they are distributed to the server tier in PDX serialized form.
• Programming Your Application to Use PdxInstances
  A PdxInstance is a lightweight wrapper around the raw bytes of the PDX serialized objects kept in the cache. It provides applications with run-time access to files of a PDX serialized object. GemFire provides the implementation of the PdxInstance class.
• Configuring PDX to Ignore Unread Fields During Deserialization
  Use the setPdxIgnoreUnreadFields API to control whether PDX ignores fields that were unread during deserialization.
• Using PdxInstanceFactory to Create PdxInstances
  You can use the PdxInstanceFactory API to create a PdxInstance from raw data when the domain class in not available on the server.
• Using C++ Enum Type with PDX Serialization
  Because there is no "object" base type in C++, enums cannot be directly passed as a parameter to the writeObject and readObject API.
• Using PDX Serialization with Delta Propagation
  To use delta propagation with PDX serialization, you must implement the Delta interface methods.
