Readable Iterator Concept
|
|
.........................
|
|
|
|
A class or built-in type ``X`` models the *Readable Iterator* concept
|
|
for value type ``T`` if, in addition to ``X`` being Assignable and
|
|
Copy Constructible, the following expressions are valid and respect
|
|
the stated semantics. ``U`` is the type of any specified member of
|
|
type ``T``.
