Enclosing class:
Object2CharFunctions
public static class Object2CharFunctions.Singleton<K>
extends AbstractObject2CharFunction<K>
implements java.io.Serializable, java.lang.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.
