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.

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:

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
