Class Short2CharFunctions.Singleton

java.lang.Object

it.unimi.dsi.fastutil.shorts.AbstractShort2CharFunction

it.unimi.dsi.fastutil.shorts.Short2CharFunctions.Singleton

All Implemented Interfaces:

Short2CharFunction, Serializable, Cloneable, Function<Short,Character>, IntUnaryOperator

Direct Known Subclasses:

Short2CharMaps.Singleton

Enclosing class:

Short2CharFunctions

public static class Short2CharFunctions.Singleton
extends AbstractShort2CharFunction
implements Serializable, Cloneable

An immutable class representing a type-specific singleton function. Note that the default return value is still settable.

Note that albeit the function is immutable, its default return value may be changed.

This class may be useful to implement your own in case you subclass a type-specific function.

Method Detail

containsKey

public boolean containsKey(short k)

Description copied from interface: Short2CharFunction

Returns true if this function contains a mapping for the specified key.

Note that for some kind of functions (e.g., hashes) this method will always return true. In particular, this default implementation always returns true.

Specified by:

containsKey in interface Short2CharFunction

Parameters:

k - the key.

Returns:

true if this function associates a value to key.

get

public char get(short k)

Description copied from interface: Short2CharFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Short2CharFunction

Parameters:

k - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.
