Method Detail

convert

public void convert(char[] input,
                    int off1,
                    int len1,
                    byte[] output,
                    int off2,
                    int len2,
                    int[] result)
             throws java.io.IOException

Description copied from class: CharacterConvertor

Converts the input chars, using the specified encoding into bytes in the given range. Conversion ends if there's no more input or if the output gets full.

Specified by:

convert in class CharacterConvertor

Parameters:

input - characters to be converted

off1 - offset position in the input arrat of the first character to be converted

len1 - count of characters to be converted

output - where output bytes are put

off2 - offset of the first output byte

len2 - count of bytes that may be used for output conversion

result - a non-null two element int[], which holds the result lengths from the conversion: result[0] contains the number of chars converted and result[1] - the number of bytes that are result of the conversion

Throws:

java.io.IOException - if there's some error during conversion

                    int off2,
                    int len2,
                    int[] result)
             throws java.io.IOException

Description copied from class: CharacterConvertor

Converts the input bytes, using the specified encoding into unicode chars. Conversion ends if there's no more input or if the output gets full.

Specified by:

convert in class CharacterConvertor

Parameters:

input - bytes to be converted

off1 - offset position in the input arrat of the first byte to be converted

len1 - count of bytes to be converted

output - where output chars are put

off2 - offset of the first output char

len2 - count of chars that may be used for output conversion

result - a non-null two element int[], which holds the result lengths from the conversion: result[0] contains the number of bytes converted and result[1] - the number of chars that are result of the conversion

Throws:

java.io.IOException - if there's some error during conversion

getMaxBytesPerChar

public int getMaxBytesPerChar()

Description copied from class: CharacterConvertor

Gets the maximum bytes that may be used for the conversion of a single char, using this CharacterConvertor's encoding.

Specified by:

getMaxBytesPerChar in class CharacterConvertor

Returns:

maximum number of bytes, necessary to convert a char.

getCharacterEncoding

public java.lang.String getCharacterEncoding()

Description copied from class: CharacterConvertor

Gets the identifier String of the encoding. This may be not the same string, which has been used for obtaining the CharacterConverter.

Specified by:

getCharacterEncoding in class CharacterConvertor

Returns:

key string for the encoding
