public class Collation extends Object
Collation defines how strings are compared and is used when creating a COLLATE expression. The COLLATE expression can be used in the WHERE clause when comparing two strings or in the ORDER BY clause when specifying how the order of the query results. CouchbaseLite provides two types of the Collation, ASCII and Unicode. Without specifying the COLLATE expression Couchbase Lite will use the ASCII with case sensitive collation by default.
