/**
* An abstract class providing basic methods for functions implementing a

*
* Optional operations just throw an {@link UnsupportedOperationException}.
* Generic versions of accessors delegate to the corresponding type-specific
* counterparts following the interface rules (they take care of returning
* null on a missing key).
*
*
* This class handles directly a default return value (including
* {@linkplain #defaultReturnValue() methods to access it}). Instances of
* classes inheriting from this class have just to return
* defRetValue to denote lack of a key in type-specific methods.
* The value is serialized.
*
*
* Implementing subclasses have just to provide type-specific
* get(), type-specific containsKey(), and
* size() methods.
