`void`	`evictInvalidatedEntries(org.apache.hc.core5.http.HttpHost host, org.apache.hc.core5.http.HttpRequest request, org.apache.hc.core5.http.HttpResponse response)`	Evicts `HttpCacheEntry`s invalidated by the given message exchange.
`java.util.List<CacheHit>`	`getVariants(CacheHit hit)`	Retrieves variant `HttpCacheEntry`s for the given hit.
`CacheMatch`	`match(org.apache.hc.core5.http.HttpHost host, org.apache.hc.core5.http.HttpRequest request)`	Returns a result with either a fully matching `HttpCacheEntry` a partial match with a list of known variants or null if no match could be found.
`CacheHit`	`store(org.apache.hc.core5.http.HttpHost host, org.apache.hc.core5.http.HttpRequest request, org.apache.hc.core5.http.HttpResponse originResponse, org.apache.hc.core5.util.ByteArrayBuffer content, java.time.Instant requestSent, java.time.Instant responseReceived)`	Stores `HttpRequest` / `HttpResponse` exchange details in the cache.
`CacheHit`	`storeFromNegotiated(CacheHit negotiated, org.apache.hc.core5.http.HttpHost host, org.apache.hc.core5.http.HttpRequest request, org.apache.hc.core5.http.HttpResponse originResponse, java.time.Instant requestSent, java.time.Instant responseReceived)`	Stores `HttpRequest` / `HttpResponse` exchange details in the cache from the negotiated `HttpCacheEntry`.
`CacheHit`	`update(CacheHit stale, org.apache.hc.core5.http.HttpHost host, org.apache.hc.core5.http.HttpRequest request, org.apache.hc.core5.http.HttpResponse originResponse, java.time.Instant requestSent, java.time.Instant responseReceived)`	Updates `HttpCacheEntry` using details from a 304 `HttpResponse` and updates the root entry if the given cache entry represents a variant.
