/**
* Interceptor that handles the wrapping and unwrapping of cached data using {@link
* org.infinispan.marshall.core.MarshalledValue}s. Known "excluded" types are not wrapped/unwrapped, which at this time
* include {@link String}, Java primitives and their Object wrappers, as well as arrays of excluded types.
*
* The {@link org.infinispan.marshall.core.MarshalledValue} wrapper handles lazy deserialization from byte array
* representations.
