boost之algorithm

algorithm

boost中将一些小的算法集中到该库，主要是一些字符串处理算法，字符串的方法需引入#include <boost/algorithm/string.hpp>

大小写转换

小写跟大写一样，就不写了：

template<typename WritableRangeT>
inline void to_upper( 
    WritableRangeT& Input, 
    const std::locale& Loc=std::locale()
)

template<typename SequenceT>
inline SequenceT to_upper_copy( 
    const SequenceT& Input, 
    const std::locale& Loc=std::locale()
)

trim

copy后缀版本就不写了：

template<typename SequenceT>
inline void trim_left(SequenceT& Input, const std::locale& Loc=std::locale())

template<typename SequenceT>
inline void trim_right(SequenceT& Input, const std::locale& Loc=std::locale())

template<typename SequenceT>
inline void trim(SequenceT& Input, const std::locale& Loc=std::locale())

split

#include <boost/algorithm/string.hpp>

int main(int argc, char const *argv[])
{
    std::vector<std::string> tokens;
    boost::split(tokens, "12 34", boost::is_any_of(" "), boost::token_compress_on);
    for (auto& t : tokens) {
        std::cout << "[" << t << "]" << std::endl;
    }

    return 0;
}

忽略大小写判断

template<typename Range1T, typename Range2T>
inline bool iequals( 
    const Range1T& Input, 
    const Range2T& Test,
    const std::locale& Loc=std::locale()
)

template<typename Range1T, typename Range2T>
inline bool istarts_with( 
    const Range1T& Input, 
    const Range2T& Test,
    const std::locale& Loc=std::locale()
)

template<typename Range1T, typename Range2T>
inline bool iends_with( 
    const Range1T& Input, 
    const Range2T& Test,
    const std::locale& Loc=std::locale()
)

template<typename Range1T, typename Range2T>
inline bool icontains( 
    const Range1T& Input, 
    const Range2T& Test, 
    const std::locale& Loc=std::locale()
)

replace

template<typename SequenceT, typename Range1T, typename Range2T>
inline void replace_first( 
    SequenceT& Input,
    const Range1T& Search,
    const Range2T& Format )

template<typename SequenceT, typename Range1T, typename Range2T>
inline void replace_last( 
    SequenceT& Input,
    const Range1T& Search,
    const Range2T& Format )

template<typename SequenceT, typename Range1T, typename Range2T>
inline void replace_all( 
    SequenceT& Input,
    const Range1T& Search,
    const Range2T& Format )
