int32_t  sourceLength,
uint8_t *  result,
int32_t  resultLength 
) const [pure virtual]

Get the sort key as an array of bytes from an UChar buffer. Sort key byte arrays are zero-terminated and can be compared using strcmp().

source string to be processed.
sourceLength length of string to be processed. If -1, the string is 0 terminated and length will be decided by the function.
result buffer to store result in. If NULL, number of bytes needed will be returned.
resultLength length of the result buffer. If if not enough the buffer will be filled to capacity.
