public abstract class AbstractReference2IntFunction<K> extends java.lang.Object implements Reference2IntFunction<K>, java.io.Serializable
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.
