public interface Portable

Portable provides an alternative serialization method. Instead of relying on reflection, each Portable is created by a registered PortableFactory.

Portable serialization that have the following advantages:

• Support multiversion of the same object type. (See SerializationConfig.setPortableVersion(int))
• Fetching individual fields without having to rely on reflection.
• Querying and indexing support without de-serialization and/or reflection.
