This tutorial covers the use of Coherence 3.7 POF annotations to extend and register objects that support serialization. Coherence 3.7 provides POF annotations, a new feature that can be used to simplify the POF process. Although it is not exceedingly complex, implementing these interfaces had a variety of advantages and disadvantages. The readExternal and writeExternal methods of this interface then do the work of marshalling and unmarshalling data into and out of a POF data stream. When working with POF, a developer typically extends a domain object to implement the .pof.PortableObject interface.

Controllable: Developers can control how POF objects are serialized and deserialized.

Versionable : POF objects can evolve over time but maintain backward compatibility.

Fast: POF objects can be serialized in less than 1/4 the time of their Java counterparts.

Small: POF objects are often 1/5 the size of objects serialized with Java.

Language independent: POF supports Java, C#, and C++.In general, you should choose POF instead of standard Java serialization because POF is: An object is marshalled into binary using POF, stored in a Coherence cache, and then unmarshalled to whatever format is appropriate for the client application. POF is a platform-independent mechanism for serializing objects into and out of a binary format.

What makes this possible are two things: Coherence*ExtendĪnd a specialized version of serialization known as Coherence Portable Object Format (POF). Instead, code is written in the language of choice, compiled against a client library, and then run. There are no special constraints on the client. While most of the code accessing Coherence is cluster-side and written in Java, Coherence clients can be written in Java. One of the more useful aspects of Coherence is its support for simple interoperability between various platforms.

Oracle Coherence 3.7 introduced the concept of POF annotations, enabling simple objects to support POF serialization without complex coding. The Portable Object Format, or POF, is a language-agnostic binary format designed to be efficient in both space and time and has become a cornerstone of Oracle Coherence. It is a critical component of working with Oracle Coherence. Serialization, or marshalling, is the process of encoding an object into a binary format.
