public abstract class ByteToCharSingleByte
extends ByteToCharConverter

A table driven conversion from byte to char for single byte character sets. The needed data tables will reside in a character set specific subclass.

Method Summary

int	convert(byte[] input, int inOff, int inEnd, char[] output, int outOff, int outEnd) Converts bytes to characters according to the selected character encoding.
int	flush(char[] output, int outStart, int outEnd) Writes any remaining output to the output buffer and resets the converter to its initial state.

flush

public int flush(char[] output,

                 int outEnd)

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).

convert

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

Converts bytes to characters according to the selected character encoding. Maintains internal state, so that conversions that result in exceptions can be restarted by calling convert again, with appropriately modified parameters. Call reset before converting input that is not a continuation of the previous call.

Specified by:

convert in class ByteToCharConverter

Parameters:

input - byte array containing text in character set

inStart - offset in input array

inEnd - offset of last byte to be converted

output - character array to receive conversion result

outStart - starting offset

outEnd - offset of last character to be written to

Returns:

the number of characters 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()
