VERSION

public static final int VERSION

Method Detail

getOptions

public static int getOptions(CollationData data,
                             CollationSettings settings,
                             char[] primaries)

Computes the options value for the compare functions and writes the precomputed primary weights. Returns -1 if the Latin fastpath is not supported for the data and settings. The capacity must be LATIN_LIMIT.

compareUTF16

public static int compareUTF16(char[] table,
                               char[] primaries,
                               int options,
                               CharSequence left,
                               CharSequence right,
                               int startIndex)
