Constructor Detail

Coder

public Coder(java.nio.charset.Charset chs)

creates an Coder for the given character set which uses a default internal buffer size for encoding.

Method Detail

setEncoder

public void setEncoder(java.nio.charset.CharsetEncoder enc,
                       int chBsize)

sets the encoder to use and requests to use a character buffer size of at least chBsize internally.

setDecoder

public void setDecoder(java.nio.charset.CharsetDecoder dec)

sets the decoder to use.

decode

public void decode(java.nio.ByteBuffer in,
                   java.lang.StringBuilder out)
            throws java.nio.charset.CharacterCodingException

decode the contents of a ByteBuffer and append them to a StringBuilder.

Parameters:

in - must be in flipped mode, i.e. ready to be read from

Throws:

java.nio.charset.CharacterCodingException

encode

public java.nio.ByteBuffer encode(java.lang.StringBuilder in,
                                  java.nio.ByteBuffer out)
                           throws java.nio.charset.CharacterCodingException

encode the contends of a StringBuilder into a ByteBuffer.

Returns:

is either the given ByteBuffer or a freshly allocated, if the given one is too short.

Throws:

java.nio.charset.CharacterCodingException
