| template<class T> ostream_joiner& operator=(const T& value); |
(1) | (library fundamentals TS v2) |
| ostream_joiner& operator=(const ostream_joiner& other) = default; |
(2) | (library fundamentals TS v2) (implicitly declared) |
| ostream_joiner& operator=(ostream_joiner&& other) = default; |
(3) | (library fundamentals TS v2) (implicitly declared) |
1) First, if the private "first element" flag is false, insert the delimiter delim into the output stream os associated with this iterator as if by os << delim;.
Then, unconditionally sets the "first element" flag to false, and insert value into the output stream as if by os << value;.
Let out_stream, delim, and first_element denote the private stream pointer, delimiter, and "first element" flag members respectively, then this function is equivalent to
if (!first_element) *out_stream << delim; first_element = false; *out_stream << value; return *this;
2-3) Implicitly declared copy/move assignment operator that copy/move assigns the private stream pointer, delimiter, and "first element" flag members.
Parameters
| value | - | the object to to be written to the stream |
| other | - | the ostream_joiner object to be assigned to this object
|
Return value
*this.
