Method Summary

Methods

Modifier and Type	Method and Description
String	decodeString(byte[] encoded) Decodes a String of characters from a byte array, taking all values (regardless of given odd), expecting only values [0,127], and decoding them to ASCII/ISO646-US characters.
String	decodeString(byte[] encoded, StringIndicators indicators) Decodes a String of characters from a byte array, taking all values (regardless of given odd), expecting only values [0,127], and decoding them to ASCII/ISO646-US characters.
byte[]	encodeString(String string) Encodes a String of characters to a byte array, accepting only ASCII/ISO646-US characters, and encoding each character according to that character set.
byte[]	encodeString(String string, StringIndicators indicators) Encodes a String of characters to a byte array, accepting only ASCII/ISO646-US characters, and encoding each character according to that character set.
IA5StringCodec<T>	getLaxDecoder() Gets an IA5StringCodec like the standard one except that decoding invalid characters produces ? characters instead of throwing an exception.
static <T> IA5StringCodec<T>	getStandardCodec() Gets the standard IA5StringCodec.

Method Detail

getStandardCodec

public static <T> IA5StringCodec<T> getStandardCodec()

Gets the standard IA5StringCodec.

Returns:

IA5StringCodec

getLaxDecoder

public IA5StringCodec<T> getLaxDecoder()

Gets an IA5StringCodec like the standard one except that decoding invalid characters produces ? characters instead of throwing an exception. The lax decoder of a lax decoder is itself (idempotent).

Specified by:

getLaxDecoder in interface StringCodec<T>

Returns:

StringCodec

encodeString

public byte[] encodeString(String string,
                  StringIndicators indicators)

Encodes a String of characters to a byte array, accepting only ASCII/ISO646-US characters, and encoding each character according to that character set. Sets an indicator to assist decoding by other StringCodecs.

Specified by:

encodeString in interface StringCodec<T>

Parameters:

string - the String to be encoded to a byte array

indicators - the StringIndicators object in which to set the indicators

Returns:

the encoded byte array

Throws:

UnsupportedDigitException - if a non-ASCII character is found

encodeString

public byte[] encodeString(String string)

Encodes a String of characters to a byte array, accepting only ASCII/ISO646-US characters, and encoding each character according to that character set.

Specified by:

encodeString in interface StringCodec<T>

Parameters:

string - the String to be encoded to a byte array

Returns:

the encoded byte array

Throws:

UnsupportedDigitException - if a non-ASCII character is found

decodeString

public String decodeString(byte[] encoded,
                  StringIndicators indicators)

Decodes a String of characters from a byte array, taking all values (regardless of given odd), expecting only values [0,127], and decoding them to ASCII/ISO646-US characters. If a value outside the range [0,127] is found, the standard decoder throws UnsupportedDigitException, while the lax decoder decodes a ? character.

Specified by:

decodeString in interface StringCodec<T>

Parameters:

encoded - the byte array to be decoded to a String

indicators - indicator values needed for decoding (ignored)

Returns:

the decoded String

Throws:

UnsupportedDigitException - if any encoded content is not in range [0,127]

decodeString

public String decodeString(byte[] encoded)

Decodes a String of characters from a byte array, taking all values (regardless of given odd), expecting only values [0,127], and decoding them to ASCII/ISO646-US characters. If a value outside the range [0,127] is found, the standard decoder throws UnsupportedDigitException, while the lax decoder decodes a ? character.

Specified by:

decodeString in interface StringCodec<T>

Parameters:

encoded - the byte array to be decoded to a String

Returns:

the decoded String

Throws:

UnsupportedDigitException - if any encoded content is not in range [0,127]
