Constructor Summary

ByteToCharISO2022()

Method Summary

int	convert(byte[] input, int inOff, int inEnd, char[] output, int outOff, int outEnd) Converts an array of bytes containing characters in an external encoding into an array of Unicode characters.
int	flush(char[] output, int outStart, int outEnd) Writes any remaining output to the output buffer and resets the converter to its initial state.
void	reset() Resets converter to its initial state.

public ByteToCharISO2022()

Method Detail

reset

public void reset()

Description copied from class: ByteToCharConverter

Resets converter to its initial state.

Specified by:

reset in class ByteToCharConverter

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

Description copied from class: ByteToCharConverter

Converts an array of bytes containing characters in an external encoding into an array of Unicode characters. This method allows a buffer by buffer conversion of a data stream. The state of the conversion is saved between calls to convert. Among other things, this means multibyte input sequences can be split between calls. If a call to convert results in an exception, the conversion may be continued by calling convert again with suitably modified parameters. All conversions should be finished with a call to the flush method.

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:

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