Expression |
Semantics |
|---|---|
|
JV(s1, s2) |
Creates a joint_view given sequences, s1 and s2. |
|
JV(jv) |
Copy constructs a joint_view from another joint_view, jv. |
|
jv = jv2 |
Assigns to a joint_view, jv, from another joint_view, jv2. |
Example
vector<int, char> v1(3, 'x'); vector<std::string, int> v2("hello", 123); joint_view< vector<int, char> , vector<std::string, int> > view(v1, v2); std::cout << view << std::endl;
