Boost库之字符串处理

equals

    assert(boost::equals("boost", "boost"));  
    assert(!boost::equals("boost", "BOOST"));  
    assert(boost::iequals("boost", "BOOST"));

all , 如果它的所有元素满足一个给定的通过判断式描述的条件，则这个条件式成立。

    assert(boost::all("\x20\t\n\r", boost::is_space()));   
    assert(boost::all("\x20\t\n\r", boost::is_classified(std::ctype_base::space)));  
    assert(boost::all("\x20\t\n\r", boost::is_any_of("\x20\t\n\r")));  
    assert(boost::all("abcde", boost::is_from_range('a','e')));  
    assert(boost::all("abcde", boost::is_from_range('a','z')));  
    assert(!boost::all("abcde", boost::is_from_range('b','c')));  
    assert(boost::all("abc __ de", boost::is_from_range('a','z') || boost::is_space() || boost::is_any_of("_")));

starts_with

    assert(boost::starts_with("boost_python-vc100-mt-1_49.dll", "boost"));  
    assert(!boost::starts_with("boost_python-vc100-mt-1_49.dll", "BOOST"));  
    assert(boost::istarts_with("boost_python-vc71-mt-1_33.dll", "BOOST"));

ends_with

    assert(boost::ends_with("boost_python-vc100-mt-1_49.dll", ".dll"));  
    assert(!boost::ends_with("boost_python-vc100-mt-1_49.dll", ".DLL"));  
    assert(boost::iends_with("boost_python-vc100-mt-1_49.dll", ".DLL"));

contains

    assert(boost::contains("boost_python-vc100-mt-1_49.dll", "python"));  
    assert(!boost::contains("boost_python-vc100-mt-1_49.dll", "PYTHON"));  
    assert(boost::icontains("boost_python-vc100-mt-1_49.dll", "PYTHON"));
