Class AbstractDouble2LongFunction

java.lang.Object

it.unimi.dsi.fastutil.doubles.AbstractDouble2LongFunction

All Implemented Interfaces:

it.unimi.dsi.fastutil.doubles.Double2LongFunction, java.io.Serializable, java.util.function.DoubleToLongFunction, java.util.function.Function<java.lang.Double,java.lang.Long>

Direct Known Subclasses:

AbstractDouble2LongMap, Double2LongFunctions.EmptyFunction, Double2LongFunctions.Singleton, Double2LongFunctions.UnmodifiableFunction

public abstract class AbstractDouble2LongFunction
extends java.lang.Object
implements it.unimi.dsi.fastutil.doubles.Double2LongFunction, 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.
