BloombergLP::bdlb::TransformIterator_Traits<RESULT(ARGUMENT), ITERATOR>

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

Synopsis

Declared in <bdlb_transformiterator.h>

template<
    class RESULT,
    class ARGUMENT,
    class ITERATOR>
struct TransformIterator_Traits<RESULT(ARGUMENT), ITERATOR>
    : TransformIterator_Traits<bsl::function<RESULT(ARGUMENT)>, ITERATOR>

Description

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.
