public static class Char2LongFunctions.Singleton extends AbstractChar2LongFunction implements java.io.Serializable, java.lang.Cloneable
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.
