public abstract class AbstractChar2ObjectFunction<V> extends Object implements Char2ObjectFunction<V>, Serializable
Optional operations just throw an 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 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.

This method must check whether the provided key is in the map using containsKey(). Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.
