(7) | (since C++20) |
Compares the contents of the underlying containers of two container adaptors. The comparison is done by applying the corresponding operator to the underlying containers.
Parameters
lhs, rhs | - | container adaptors whose contents to compare |
-T must meet the requirements of EqualityComparable. |
Return value
1-6)
true
if the corresponding comparison yields
true
,
false
otherwise.
7) Result of three-way comparison on underlying containers.
Complexity
Linear in the size of the container.
