Public methods

getDirectionalities

added in API level 1
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.

Parameters
src char

dest byte

count int

getEastAsianWidth

added in API level 8
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 the East Asian Width for input

getEastAsianWidths

added in API level 8
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

getMirror

added in API level 1
public static char getMirror (char ch)

Return the right-to-left mirror (or the original char if none) of the specified char.

Parameters
ch char

Returns
char

mirror

added in API level 1
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
text char: array of characters to apply mirror operation

start int: first character in array to mirror

count int: maximum number of characters to mirror

Returns
boolean true if replacements were made
