在Boost的Function功能中,用到了Boost的Preprocessor,在这部分中Boost提供的宏预处理功能是很强大的,主要的宏功能有重复生成(BOOST_PP_REPEAT_FROM_TO),条件判断(BOOST_PP_IF),连接(BOOST_PP_CAT),数值比较(BOOST_PP_GREATER),参数枚举(BOOST_PP_ENUM_PARAMS)等,使用这些宏,可以按照自己的需要用宏生成模板类或者...
辅助宏方面，PP库包含了诸如Tuple、ARRAY、List等容器类，为用户提供了便捷的宏操作工具。其计算模块则支持256以内整数的四则运算，有效提高了宏计算的效率。相比传统宏仅进行展开而不进行计算，PP库的宏计算功能在某些情况下能显著提升性能。重复产生功能允许用户通过宏迭代轻松生成重复代码，如使用REPEAT宏...
BOOST_PP_REPEAT _2_256 and so on. My understanding (which I tried to convey in my post) is that such macros are generated by a program. That program is admittedly not part of the library as distributed (I believe it is part of ...
Admittedly, this formula is tedious to repeat, especially on a project with many polymorphic classes. That it is neccessary reflects some limitations in C++'s compile-time introspection capabilities: there's no way to enumerate the members of a class and find out which are virtual functions. At...
In part 1, learn the basics of working with repeat controls by following the steps to build an XPage where users can get names from a Domino Directory by clicking on an alphabetic pager. Then, in part 2, learn to harness the power of nested repeat controls to handle complex data ...
Commits on Sep 9, 2020 Explicitly specify PP_REPEAT nesting level to nested Boost.Preprocess… … …or macros. This adds a Boost.Log-side workaround for a bug in the new MSVC-14.2 preprocessor enabled with /Zc:preprocessor. The bug still affects other libraries, like Boost.Phoenix. This ...
These recombinants merged the RI region with the three central repeat regions of different CSP alleles (VK210, VK247, and P. vivax-like), and also contained N- and C-terminal (yPvCSP-AllFL) or only C-terminal (yPvCSP-AllCT) regions from P. vivax CSP. In addition, we also used ...
