+ * @enum OSLogEntryStoreCategory
+ *

+ * A classification of how the entry was to be stored and
+ * rotated at the point when it was created.
+ *
+ * @discussion
+ * The unified logging system keeps entries in one of two
+ * places: a ring buffer in memory and a persisted data store.
+ * Entries are rotated out of both places to free up resources.
+ * This rotation is not strictly aligned with entries'
+ * timestamps --- in particular, they can be rotated in bulk,
+ * and they are rotated according to a series of heuristics that
+ * take into account space, time, and how the entries were
+ * classified.
+ *
+ * @constant OSLogEntryStoreCategoryMetadata
+ * This entry was generated as information about the other
+ * entries or about the sequence of entries as a whole.
+ *
+ * @constant OSLogEntryStoreCategoryShortTerm
+ * This entry was not intended to be long-lived and was captured
+ * in the ring buffer.
+ *
+ * @constant OSLogEntryStoreCategoryLongTermAuto
+ * The entry was intended to be persisted in a filesystem-backed
+ * data store and kept mainly based on the amount of space
+ * available.
+ *
+ * @constant OSLogEntryStoreCategoryLongTerm1
+ * @constant OSLogEntryStoreCategoryLongTerm3
+ * @constant OSLogEntryStoreCategoryLongTerm7
+ * @constant OSLogEntryStoreCategoryLongTerm14
+ * @constant OSLogEntryStoreCategoryLongTerm30
+ * The entry was tagged with a hint indicating that the system
+ * should try to preserve it for a certain amount of time. It
+ * was persisted in the filesystem-backed data store, and
+ * rotation of these entries was based on both time and space
+ * considerations.
