+ * A specialized map implementation for use with enum type keys.
+ *
+ * All of the keys in an enum map must come from a single enum type that is specified, when the map is created. Enum
+ * maps are represented internally as arrays. This representation is extremely compact and efficient.
+ *
+ * Enum maps are maintained in the natural order of their keys (the order in which the enum constants are declared).
+ * This is reflected in the iterators returned by the collection views {@see self::getIterator()} and
+ * {@see self::values()}.
+ *
+ * Iterators returned by the collection views are not consistent: They may or may not show the effects of modifications
+ * to the map that occur while the iteration is in progress.
