public CharToByteEUC_TW()

Method Detail

flush

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

Description copied from class: CharToByteConverter

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

Specified by:

flush in class CharToByteConverter

Parameters:

output - byte 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. Will occur if the input buffer on the last call to convert ended with the first character of a surrogate pair. 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.

reset

public void reset()

Description copied from class: CharToByteConverter

Resets converter to its initial state.

Specified by:

reset in class CharToByteConverter

canConvert

public boolean canConvert(char ch)

Description copied from class: CharToByteConverter

Returns true if the given character can be converted to the target character encoding.

Overrides:

canConvert in class CharToByteConverter

Parameters:

ch - character to test

Returns:

true if given character is translatable, false otherwise.

convert

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

Character conversion

Specified by:

convert in class CharToByteConverter

Parameters:

input - array containing Unicode characters to be converted.

inOff - begin conversion at this offset in input array.

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

output - byte 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 the external character encoding. Thrown only when converter is not in substitution mode.

MalformedInputException - if the input buffer contains any sequence of chars that is illegal in Unicode (principally unpaired surrogates and ? or ?). After this exception is thrown, the method nextCharIndex can be called to obtain the index of the first invalid input character. The MalformedInputException can be queried for the length of the invalid input.

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

getMaxBytesPerChar

public int getMaxBytesPerChar()

returns the maximum number of bytes needed to convert a char

Specified by:

getMaxBytesPerChar in class CharToByteConverter

getCharacterEncoding

public String getCharacterEncoding()

Return the character set ID

Specified by:

getCharacterEncoding in class CharToByteConverter

getNative

protected int getNative(char unicode)

searchTab

protected int searchTab(char code,
                        char[] table)
