/**
* Dedicated <code>Map</code> implementation to simplify remote invocation of service methods that accept custom object input.
* This map is backed by an internal map that holds already serialized content to avoid additional serialization on sending time.
* That removes the burden of ensuring that container will know about all custom data model classes as part of global classpath.
*
* This implementation does not support all methods that are usually not used when sending data. It shall be considered only as a wrapper
* and not actual and complete implementation of a map.
