returns the ratio of cache requests which were misses . this is defined as misscount / requestcount , or 0.0 when requestcount == 0 . note that hitrate + missrate = ~ 1.0 . cache misses include all requests which were n't cache hits , including requests which resulted in either successful or failed loading attempts , and requests which waited for other threads to finish loading . it is thus the case that misscount > = loadsuccesscount + loadexceptioncount . multiple concurrent misses for the same key will result in a single load operation . concode_field_sep long totalLoadTime concode_elem_sep long evictionCount concode_elem_sep long hitCount concode_elem_sep long loadSuccessCount concode_elem_sep long missCount concode_elem_sep long loadExceptionCount concode_field_sep long requestCount concode_elem_sep CacheStats minus concode_elem_sep long totalLoadTime concode_elem_sep long evictionCount concode_elem_sep long hitCount concode_elem_sep double hitRate concode_elem_sep CacheStats plus concode_elem_sep long loadCount concode_elem_sep double averageLoadPenalty concode_elem_sep int hashCode concode_elem_sep long loadSuccessCount concode_elem_sep boolean equals concode_elem_sep String toString concode_elem_sep double loadExceptionRate concode_elem_sep long missCount concode_elem_sep long loadExceptionCount
