Traits for a transform iterator whose functor is a function type.

struct TransformIterator_Traits<RESULT(ARGUMENT), ITERATOR>
: TransformIterator_Traits<bsl::function<RESULT(ARGUMENT)>, ITERATOR>Specialize the transform iterator traits template for functors that are function types. It is sufficient to inherit from the version of the traits class that corresponds to a bsl::function of the function type parameter.
| Name | Description |
|---|---|
TransformIterator_Traits<bsl::function<RESULT(ARGUMENT)>, ITERATOR> | This component-private class defines various types that are used in the implementation of the transform iterator. |
| Name | Description |
|---|---|
BaseIteratorTraits | Define the iterator traits class of the underlying iterator. |
ResultType | Result type of applying the functor to a dereferenced iterator. |
difference_type | Type used to represent distances between iterators. |
iterator_category | Iterator category of this transform iterator. |
pointer | Pointer type derived from the functor result type. |
reference | Reference type returned by dereferencing this iterator. |
value_type | Value type produced by applying the functor to a dereferenced underlying iterator. |
