* <p>
* Implementations should allow a value to be looked up from a key and
* a key to be looked up from a value with equal performance.
+ * <p>
+ * This map enforces the restriction that there is a 1:1 relation between
+ * keys and values, meaning that multiple keys cannot map to the same value.
+ * This is required so that "inverting" the map results in a map without
+ * duplicate keys. See the {@link #put} method description for more information.
