Method Detail

flush

public int flush(char[] output,
                 int outStart,
                 int outEnd)
          throws MalformedInputException

Description copied from class: ByteToCharConverter

Writes any remaining output to the output buffer and resets the converter to its initial state.

Specified by:

flush in class ByteToCharConverter

Parameters:

output - char array to receive flushed output.

outStart - start writing to output array at this offset.

outEnd - stop writing to output array at this offset (exclusive).

Throws:

MalformedInputException - if the output to be flushed contained a partial or invalid multibyte character sequence. flush will write what it can to the output buffer and reset the converter before throwing this exception. An additional call to flush is not required.

convert

public int convert(byte[] input,
                   int inOff,
                   int inEnd,
                   char[] output,
                   int outOff,
                   int outEnd)
            throws UnknownCharacterException,
                   MalformedInputException,
                   ConversionBufferFullException

Character conversion

Specified by:

convert in class ByteToCharConverter

Parameters:

input - byte array containing text to be converted.

inOff - begin conversion at this offset in input array.

inEnd - stop conversion at this offset in input array (exclusive).

output - character array to receive conversion result.

outOff - start writing to output array at this offset.

outEnd - stop writing to output array at this offset (exclusive).

Returns:

the number of bytes written to output.

Throws:

UnknownCharacterException - for any character that that cannot be converted to Unicode. Thrown only when converter is not in substitution mode.

MalformedInputException - if the input buffer contains any sequence of bytes that is illegal for the input character set.

ConversionBufferFullException - if output array is filled prior to converting all the input.

reset

public void reset()

Resets the converter.

Specified by:

reset in class ByteToCharConverter
