Also added an import into the boost::detail namespace for backward compatibility with Boost.Range. Added a pure_iterator_traversal metafunction that automatically converts iterator category as well.
This change excludes boost:: and boost::detail:: namespaces from ADL for unqualified function calls (e.g. algorithms). This reduces the possibility of name clashes with other libraries and user's code. One of the effects should be fixing test failures on gcc 4.2 and 4.4 due to clashed with Boost.TypeTraits.
Also some of the functions marked with inline keyword.
This makes iterators defined using iterator_facade more friendly to type inspection and fixes its use with next()/prior() since commit https://github.com/boostorg/utility/commit/651a869d4f9479dd3dfdd0293305a60b8c8d0e1c.
The arithmetic, indexing and relational operators are only defined if the iterator category or traversal permits that. Note that the implementation requires partial template specialization support now.
Reverted: 2e099caceb9..21102938e8ccb
I'm going to reapply some of them soon, but it's easier to revert them
all first, as there are conflicts. Also the number of changes that were
inserted since then, mean that there would be a huge gap between related
changes.
Added a test for pointee
Fixed iterator_facade so operator[] result type computation didn't
cause a problem with abstract types.
Updated iterator_facade operator[] docs for accuracy.
Allowed Borland to simply fail the indirect_iterator_member_types test
because of its lame const-dropping, instead of trying to work around
it.
[SVN r21579]
is_incrementable.hpp: checks whether ++x is well-formed
pointee.hpp: value_type of iterators or smart pointers
indirect_reference.hpp: reference type of iterators or smart pointers
indirect_iterator.hpp
indirect_iterator_member_types.cpp
Use pointee/indirect_reference to select value/reference type.
iterator_concepts.hpp: Fixed interoperable test. Hardly tests enough, but it's a start
minimum_category.hpp: Better error messages for vc6
indirect_iterator_test.cpp: Workarounds for compilers without SFINAE
static_assert_same.hpp: Informative error reports; added a macro.
zip_iterator_test.hpp: Added missing #include
Jamfile: made zip_iterator test pass with vc6/stlport
[SVN r21514]
- The logic for determining the result of iterator_facade::operator[] has been factored out into a separate detail header in preparation for its potential use in iterator_range to avoid iterator_range::operator[] from returning a reference to a temporary.
