Class AbstractByte2FloatFunction

java.lang.Object

it.unimi.dsi.fastutil.bytes.AbstractByte2FloatFunction

All Implemented Interfaces:

Byte2FloatFunction, Function<Byte,Float>, Serializable, Function<Byte,Float>, IntToDoubleFunction

Direct Known Subclasses:

AbstractByte2FloatMap, Byte2FloatFunctions.EmptyFunction, Byte2FloatFunctions.Singleton, Byte2FloatFunctions.UnmodifiableFunction

public abstract class AbstractByte2FloatFunction
extends Object
implements Byte2FloatFunction, 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.

Method Details

defaultReturnValue

public void defaultReturnValue(float rv)

Description copied from interface: Byte2FloatFunction

Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.

Specified by:

defaultReturnValue in interface Byte2FloatFunction

Parameters:

rv - the new default return value.

defaultReturnValue

public float defaultReturnValue()

Description copied from interface: Byte2FloatFunction

Gets the default return value.

This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).

Specified by:

defaultReturnValue in interface Byte2FloatFunction

Returns:

the current default return value.
