BCodec

public class BCodec extends RFC1522Codec implements StringEncoder,StringDecoder(Code)

Identical to the Base64 encoding defined by RFC 1521 and allows a character set to be specified.

RFC 1522 describes techniques to allow the encoding of non-ASCII text in various portions of a RFC 822 [2] message header, in a manner which is unlikely to confuse existing message handling software.

Constructor Detail

BCodec
public BCodec()(Code)
	Default constructor.

BCodec
public BCodec(String charset)(Code)
	Constructor which allows for the selection of a default charset Parameters: charset - the default string charset to use. See Also: JRE character * encoding names

Method Detail

decode
public String decode(String value) throws DecoderException(Code)
	Decodes a Base64 string into its original form. Escaped characters are converted back to their original representation. Parameters: value - Base64 string to convert into its original form original string throws: DecoderException - A decoder exception is thrown if a failure condition is encountered during the decode process.

decode
public Object decode(Object value) throws DecoderException(Code)
	Decodes a Base64 object into its original form. Escaped characters are converted back to their original representation. Parameters: value - Base64 object to convert into its original form original object throws: DecoderException - A decoder exception is thrown if a failure condition is encountered during the decode process.

doDecoding
protected byte[] doDecoding(byte[] bytes) throws DecoderException(Code)

doEncoding
protected byte[] doEncoding(byte[] bytes) throws EncoderException(Code)

encode
public String encode(String value, String charset) throws EncoderException(Code)
	Encodes a string into its Base64 form using the specified charset. Unsafe characters are escaped. Parameters: value - string to convert to Base64 form Parameters: charset - the charset for pString Base64 string throws: EncoderException - thrown if a failure condition is encountered during the encoding process.

encode
public String encode(String value) throws EncoderException(Code)
	Encodes a string into its Base64 form using the default charset. Unsafe characters are escaped. Parameters: value - string to convert to Base64 form Base64 string throws: EncoderException - thrown if a failure condition is encountered during the encoding process.

encode
public Object encode(Object value) throws EncoderException(Code)
	Encodes an object into its Base64 form using the default charset. Unsafe characters are escaped. Parameters: value - object to convert to Base64 form Base64 object throws: EncoderException - thrown if a failure condition is encountered during the encoding process.

getDefaultCharset
public String getDefaultCharset()(Code)
	The default charset used for string decoding and encoding. the default string charset.

getEncoding
