7.5.2. VersionAwareMarshaller

PDF

As the name suggests, this Marshaler adds a version short to the start of any stream when writing, enabling similar VersionAwareMarshaller instances to read the version short and know which specific Marshaler implementation to delegate the call to. For example, CacheMarshaller200 is the Marshaler for JBoss Cache 2.0.x. JBoss Cache 3.0.x ships with CacheMarshaller300 with an improved wire protocol. Using a VersionAwareMarshaller helps achieve wire protocol compatibility between minor releases but still affords us the flexibility to tweak and improve the wire protocol between minor or micro releases.
