Coding Standards
A class or built-in type X models the Incrementable Iterator concept if, in addition to X being Assignable and Copy Constructible, the following expressions are valid and respect the stated semantics.
Incrementable Iterator Requirements (in addition to Assignable, Copy Constructible) | ||
---|---|---|
Expression | Return Type | Assertion/Semantics |
++r | X& | &r == &++r |
r++ | X | { X tmp = r; ++r; return tmp; } |
iterator_traversal<X>::type | Convertible to incrementable_traversal_tag |
