BloombergLP::bslstl::ForwardIterator

Synopsis

Declared in <bslstl_forwarditerator.h>

template<
    class T,
    class ITER_IMP,
    class TAG_TYPE = std::forward_iterator_tag>
class ForwardIterator;

Description

Given an ITER_IMP type that implements a minimal subset of an iterator interface, this template generates a complete iterator that meets all of the requirements of a "forward iterator" in the C++ standard. If T is const-qualified, then the resulting type is a const iterator. T shall not be a function, reference type or void. ITER_IMP must provide public operations so that, for objects i and j of type ITER_IMP, the following operations are supported: ` ITER_IMP i; Default construction ITER_IMP j(i); Copy construction i = j Assignment ++i Increment to next element i == j // convertible to bool Equality comparison *i // reference convertible to T& Element access (dereference) `
