Public methods
getDirectionalities
public static void getDirectionalities (char[] src, byte[] dest, int count)
Fill in the first count
bytes of dest
with the
directionalities from the first count
chars of src
.
This is just like Character.getDirectionality() except it is a
batch operation.

src |
char |
dest |
byte |

getEastAsianWidth
public static int getEastAsianWidth (char input)
Calculate the East Asian Width of a character according to
Unicode TR#11. The return
will be one of EAST_ASIAN_WIDTH_NEUTRAL
,
EAST_ASIAN_WIDTH_AMBIGUOUS
, EAST_ASIAN_WIDTH_HALF_WIDTH
,
EAST_ASIAN_WIDTH_FULL_WIDTH
, EAST_ASIAN_WIDTH_NARROW
,
or EAST_ASIAN_WIDTH_WIDE

Parameters | |
---|---|
input |
char : the character to measure |
Returns | |
---|---|
int |

getEastAsianWidths
public static void getEastAsianWidths (char[] src, int start, int count, byte[] dest)
Fill the first count
bytes of dest
with the
East Asian Width from count
chars of src
starting at start
. East Asian Width is calculated based on
Unicode TR#11. Each entry
in dest
will be one of EAST_ASIAN_WIDTH_NEUTRAL
,
EAST_ASIAN_WIDTH_AMBIGUOUS
, EAST_ASIAN_WIDTH_HALF_WIDTH
,
EAST_ASIAN_WIDTH_FULL_WIDTH
, EAST_ASIAN_WIDTH_NARROW
,
or EAST_ASIAN_WIDTH_WIDE
.
Parameters | |
---|---|
src |
char : character array of input to measure |
start |
int : first character in array to measure |
count |
int : maximum number of characters to measure |
dest |
byte : byte array of results for each character in src |

public static boolean mirror (char[] text, int start, int count)
Replace the specified slice of text
with the chars'
right-to-left mirrors (if any), returning true if any
replacements were made.
Parameters | |
