public abstract class AbstractInt2DoubleFunction
extends Object
implements Int2DoubleFunction, 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.
