  - ### Method Detail

    - #### createRoot

          public HttpCacheEntry createRoot(HttpCacheEntry latestVariant,
                                           Collection<String> variants)

      Creates a new root `HttpCacheEntry` (parent of multiple variants).
      Parameters:
        `latestVariant` - The most recently created variant entry
        `variants` - describing cache entries that are variants of this parent entry; this maps a "variant key" (derived from the varying request headers) to a "cache key" (where in the cache storage the particular variant is located)

    - #### create

          public HttpCacheEntry create(Instant requestInstant,
                                       Instant responseInstant,
                                       org.apache.hc.core5.http.HttpHost host,

                                       Resource resource)

      Create a new `HttpCacheEntry` with the given `Resource`.
      Parameters:
        `requestInstant` - Date/time when the request was made (Used for age calculations)
        `responseInstant` - Date/time that the response came back (Used for age calculations)
        `host` - Target host
        `request` - Original client request (a deep copy of this object is made)
        `response` - Origin response (a deep copy of this object is made)
        `resource` - Resource representing origin response body

    - #### createUpdated

          public HttpCacheEntry createUpdated(Instant requestInstant,
                                              Instant responseInstant,
                                              org.apache.hc.core5.http.HttpHost host,
