public abstract class AbstractReference2ReferenceFunction<K,​V>
extends java.lang.Object
implements Reference2ReferenceFunction<K,​V>, java.io.Serializable
An abstract class providing basic methods for functions implementing a type-specific interface.

This class handles directly a default return value (including 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.
