[multiple changes] 2005-03-31 Chris Jefferson <chris@bubblescope.net> * include/tr1/tuple: Support iteration via tuple_iterate.h. * include/tr1/tuple_iterate.h: Iteration file for tuple. 2005-03-31 Douglas Gregor <doug.gregor@gmail.com> * include/Makefile.am (tr1_headers): Add bind and mu repetition headers and reference_wrapper<> forwarding header. * include/Makefile.in: Regenerate. * include/tr1/bind_iterate.h: Implementation of function call operators for the function object returned from tr1::bind(). * include/tr1/bind_repeat.h: Bind-specific repetition header, akin to include/tr1/repeat.h. * include/tr1/functional (_Mem_fn): Bug fix: declare result member template for use with result_of. (is_bind_expression): New. (is_placeholder): New. (_Placeholder): New. Placeholder type for bind. (_Mu): New. Implementation detail of bind. (_Bind, _Bind_result): New. Function objects returned by bind. (_GLIBCXX_JOIN): New. Required to create bind placeholders. * include/tr1/functional_iterate.h (_Bind, _Bind_result, bind): New. Implementation of tr1::bind. * include/tr1/mu_iterate.h (_Mu): result template and operator() for the _Mu helper to bind. * include/tr1/ref_fwd.h (reference_wrapper): Forward declaration used by tuple header. (ref): Ditto. (cref): Ditto. * include/tr1/repeat.h: Add bind-specific repetition macros. * include/tr1/tuple: Use reference_wrapper forwarding header for initial definitions, then include <tr1/functional> at the end, to make the circular dependencies work. (tie): Support zero-argument tie() function. * testsuite/tr1/3_function_objects/bind/all_bound.cc: New test of bind() functionality with parameters bound. * testsuite/tr1/3_function_objects/bind/nested.cc: New test of nested bind() expressions. * testsuite/tr1/3_function_objects/bind/placeholders.cc: New test of bind() placeholders. * testsuite/tr1/3_function_objects/bind/ref.cc: New test of bind() with arguments bound via reference_wrapper<>. * scripts/gen_includers.pl: Generate the repetitive part of include/tr1/repeat.h. * scripts/gen_bind_includers.pl: Generate the repetitive part of include/tr1/bind_repeat.h.
