Assignment operators

== Synopses

Declared in `<bslstl_map.h>`

Assign to this object the value and comparator of the specified `rhs` object, propagate to this object the allocator of `rhs` if the `ALLOCATOR` type has trait `propagate_on_container_copy_assignment`, and return a reference providing modifiable access to this object. If an exception is thrown, `*this` is left in a valid but unspecified state. This method requires that the (template parameter) types `KEY` and `VALUE` both be `copy‐assignable` and `copy‐insertable` into this map (see {Requirements on `KEY` and `VALUE`}).

Assign to this object the value resulting from first clearing this map and then inserting each `value_type` object in the specified `values` initializer list, ignoring those objects having a key equivalent to that which appears earlier in the list; return a reference providing modifiable access to this object. This method requires that the (template parameter) types `KEY` and `VALUE` both be `copy‐insertable` into this map (see {Requirements on `KEY` and `VALUE`}).
