std::basic_regex::assign(3) C++ Standard Libary std::basic_regex::assign(3) NAME std::basic_regex::assign - std::basic_regex::assign Synopsis basic_regex& assign( const basic_regex& other ); (1) (since C++11) basic_regex& assign( basic_regex&& other ) noexcept; (2) (since C++11) basic_regex& assign( const CharT* s, (3) (since C++11) flag_type f = std::regex_constants::ECMAScript ); basic_regex& assign( const CharT* ptr, size_t count, (4) (since C++11) flag_type f = std::regex_constants::ECMAScript ); template< class ST, class SA > basic_regex& assign( const std::basic_string<CharT,ST,SA>& str, (5) (since C++11) flag_type f = std::regex_constants::ECMAScript ); template< class InputIt > basic_regex& assign( InputIt first, InputIt last, (6) (since C++11) flag_type f = std::regex_constants::ECMAScript ); basic_regex& assign( std::initializer_list<CharT> ilist, (7) (since C++11) flag_type f = std::regex_constants::ECMAScript ); Assigns the contents to the regular expression. 1) Assigns the contents of other. flags() and mark_count() are equivalent to the values of other.flags() and other.mark_count() after the call. 2) Assigns the contents of other using move semantics. flags() and mark_count() are equivalent to the values of other.flags() and other.mark_count() be- fore the assignment. After the call, other is in a valid, but unspecified state. 3-7) Assigns a sequence of characters to the regular expression. The syntax flags are set to f. mark_count() returns the number of marked subexpres- sions within the resulting subexpression after the call. 3) Assigns a null-terminated string pointed to by s. 4) Assigns a sequence of count characters, pointed to by s. 5) Assigns the string str. 6) Assigns the characters in the range [first, last). 7) Assigns the characters in the initializer list ilist. Parameters other - another regular expression to assign s - pointer to a character sequence to assign str - string to assign first, last - the range of characters to assign ilist - initializer list containing characters to assign Type requirements - InputIt must meet the requirements of LegacyInputIterator. Return value *this Exceptions 1) May throw implementation-defined exceptions. 3-7) std::regex_error if the supplied regular expression is not valid. The object is not modified in that case.
