(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.
