Writable Iterator Concept
|
|
.........................
|
|
|
|
A class or built-in type ``X`` models the *Writable Iterator* concept
|
|
if, in addition to ``X`` being Copy Constructible, the following
|
|
expressions are valid and respect the stated semantics. Writable
|
|
Iterators have an associated *set of value types*.
