Assigns the contents to the regular expression.
Assigns the contents of other. flags() and mark_count() are equivalent to the values of other.flags() and other.mark_count() after the call.
Assigns the contents of other using move semantics. flags() and mark_count() are equivalent to the values of other.flags() and other.mark_count() before 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 subexpressions within the resulting subexpression after the call.
Assigns a null-terminated string pointed to by s.
Assigns a sequence of count characters, pointed to by s.
Assigns the string str.
Assigns the characters in the range
[first,last).Assigns the characters in the initializer list ilist.
[edit] 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. |
[edit] Return value
*this
[edit] Exceptions
- 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.
