比较sub_match另一个sub_match、字符串、以空结尾的字符序列或字符。
1-6%29比较两sub_match直接通过比较它们的潜在字符序列。好像是由lhs.compare(rhs)
7-18%29比较asub_match带着std::basic_string.执行似由sm.compare(typename sub_match<BidirIt>::string_type(st.data(), st.size())，在哪里sm是sub_match争论和st是basic_string争论。
19-30%29比较asub_match以空结尾的字符串。好像是由sm.compare(s)，在哪里sm是sub_match和s指向以空结尾的字符串的指针。
31-42%29比较asub_match和一个角色。好像是由sm.compare(typename sub_match<BidirIt>::string_type(1, ch))，在哪里sm是sub_match和ch是个角色。
参数
| lhs, rhs | - | a sub_match, basic_string, pointer to a null-terminated string or a character to compare |
|---|
返回值
true如果相应的比较符合std::sub_match::compare()，，，false否则。
例
另见
| compare | compares matched subsequence (if any) (public member function) |
|---|
