Collation

public final class Collation

Collation factory. 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.

  • Creates an ASCII collation that will compare two strings by using binary comparison.

    Declaration

    Swift

    static public func ascii() -> ASCII

    Return Value

    The ASCII collation.

  • Creates a Unicode collation that will compare two strings by using Unicode Collation Algorithm. If the locale is not specified, the collation is Unicode-aware but not localized; for example, accented Roman letters sort right after the base letter (This is implemented by using the en_US locale.).

    Declaration

    Swift

    static public func unicode() -> Unicode

    Return Value

    The Unicode collation.

  • ASCII collation compares two strings by using binary comparison.
