question: returns the ratio of cache loading attempts which threw exceptions . this is defined as loadexceptioncount / loadsuccesscount + loadexceptioncount , or 0.0 when loadsuccesscount + loadexceptioncount == 0 . 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 missRate concode_elem_sep long missCount concode_elem_sep long loadExceptionCount
target: double function ( ) { long loc0 = loadSuccessCount + loadExceptionCount ; return ( loc0 == 0 ) ? 0.0 : ( double ) loadExceptionCount / loc0 ; }
