operator== (multimap) (STL/CLR)

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at operator== (multimap) (STL/CLR).

List equal comparison.

template<typename Key,  
    typename Mapped>  
    bool operator==(multimap<Key, Mapped>% left,  
        multimap<Key, Mapped>% right);  

Parameters

left
Left container to compare.

right
Right container to compare.

The operator function returns true only if the sequences controlled by left and right have the same length and, for each position i, left``[i] == right``[i]. You use it to test whether left is ordered the same as right when the two multimaps are compared element by element.

 [a 1] [b 2] [c 3]  
 [a 1] [b 2] [d 4]  
[a b c] == [a b c] is True  
[a b c] == [a b d] is False
