Serialized Fields

hashCode

int hashCode

Cache the hashCode the first time hashCode() is called to avoid cost of recomputing in applications that rely on HashSets or HashMaps of Permutations, etc with heavy use of the hashCode.

hashCodeIsCached

boolean hashCodeIsCached

Flag for validating/invalidating cache of hashCode. All methods that change state of Permutation must invalidate the cache.

permutation

int[] permutation

Raw permutation, which should consist of a permutation of the integers in [0, permutation.length).
