public CharsetDecoderBOCU(CharsetICU cs)

Method Details

decodeBocu1LeadByte

private int decodeBocu1LeadByte(int b)

Function for BOCU-1 decoder; handles multi-byte lead bytes.

Parameters:

b - lead byte; BOCU1_MINinvalid input: '<'=binvalid input: '<'BOCU1_START_NEG_2 or BOCU1_START_POS_2invalid input: '<'=binvalid input: '<'BOCU1_MAX_LEAD

Returns:

(diffinvalid input: '<'invalid input: '<'2)|count

decodeBocu1TrailByte

private int decodeBocu1TrailByte(int countValue,
 int b)

Function for BOCU-1 decoder; handles multi-byte trail bytes.

Parameters:

b - trail byte

count - number of remaining trail bytes including this one

Returns:

new delta for diff including b - invalid input: '<'0 indicates an error
