Field Details

END_OF_SUBTAG

public static final int END_OF_SUBTAG

Bit flag used on the last character of a subtag in the trie. Must be set consistently by the builder and the lookup code.

DISTANCE_SKIP_SCRIPT

public static final int DISTANCE_SKIP_SCRIPT

Distance value bit flag, set by the builder.

INSTANCE

Method Details

shiftDistance

public static final int shiftDistance(int distance)

getShiftedDistance

public static final int getShiftedDistance(int indexAndDistance)

getDistanceDouble

public static final double getDistanceDouble(int indexAndDistance)

getDistanceFloor

public static final int getDistanceFloor(int indexAndDistance)

getIndex

public static final int getIndex(int indexAndDistance)

testOnlyDistance

public int testOnlyDistance(ULocale desired,
 ULocale supported,
 int threshold,
 LocaleMatcher.FavorSubtag favorSubtag)

getBestIndexAndDistance

public int getBestIndexAndDistance(LSR desired,
 LSR[] supportedLSRs,
 int supportedLSRsLength,
 int shiftedThreshold,
 LocaleMatcher.FavorSubtag favorSubtag,
 LocaleMatcher.Direction direction)

Finds the supported LSR with the smallest distance from the desired one. Equivalent LSR subtags must be normalized into a canonical form.

Returns the index of the lowest-distance supported LSR in the high bits (negative if none has a distance below the threshold), and its distance (0..ABOVE_THRESHOLD) in the low bits.
