Re: Ada-Singleton-Why does it work like this?

Yet another question, if my Singleton_Type is unconstrained, why does
Ada allow creating Access-Types to unconstrained types allowing to
access there record-properties, while not allowing to create an
instance of Singleton_Type directly? I thought that Ada demands a
declaration of an instance before creating an Access-Type to access
it? Maybe I´m mixing in C++, but if I declare a pointer in C++ I
either have to create a new instance using "new" in heap-memory where
the pointer points to or I have to use references and then let the
pointer point to a reference. In both cases I first have to create an
object and then let the pointer point to it. When I use access types
in Ada in my example it´s possible to create a pointer to a class
which can´t be instantiated, because it is unconstrained. Though it
works to access the record-properties using the access-type. Could
anyone tell me what I´m getting wrong concerning Ada?

Thank you!
