it.unimi.dsi.fastutil.floats.AbstractFloat2DoubleFunction

All Implemented Interfaces:: Float2DoubleFunction, Function<Float,Double>, Serializable, DoubleUnaryOperator, Function<Float,Double>

Direct Known Subclasses:: AbstractFloat2DoubleMap, Float2DoubleFunctions.EmptyFunction, Float2DoubleFunctions.Singleton, Float2DoubleFunctions.UnmodifiableFunction

public abstract class AbstractFloat2DoubleFunction
extends Object
implements Float2DoubleFunction, 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.
