public abstract class AbstractLong2IntFunction
extends java.lang.Object
implements it.unimi.dsi.fastutil.longs.Long2IntFunction, 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.
