19.3.2. Protocol Interoperability Over REST

When data is stored via the REST interface the values are interpreted by embedded, Hot Rod or Memcached clients as a sequence of bytes. Meaning is given to this byte-sequence using the MIME type specified via the "Content-Type" HTTP header, but the content type information is only available to REST clients. No specific interoperability configuration is required for this to occur.

When retrieving data via REST, primitive types stored are read in their primitive format. If a UTF-8 String has been stored via Hot Rod, Embedded, or Memcached, it will be retrieved as String from REST. If custom objects have been serialized and stored via the embedded or remote cache, these can be retrieved as application/x-java-serialized-object, application/xml, or application/json. Any other byte arrays are treated as application/octet-stream.
