Method Summary

Methods

Modifier and Type	Method and Description
String	decodeString(byte[] encoded) Decodes a String of characters from a byte array, taking length values from octets, rejecting any value that isn't in range [0,9], and decoding to characters ['0','9'].
String	decodeString(byte[] encoded, StringIndicators indicators) Decodes a String of characters from a byte array, taking length values from octets, rejecting any value that isn't in range [0,9], and decoding to characters ['0','9'].
byte[]	encodeCharArray(char[] chars) Encodes an array of characters to a byte array, accepting only decimal digit characters ['0','9'], and encoding each digit in an octet as [0,9].
byte[]	encodeString(String string) Encodes a String of characters to a byte array, accepting only decimal digit characters ['0','9'], and encoding each digit in an octet as [0,9].
byte[]	encodeString(String string, StringIndicators indicators) Encodes a String of characters to a byte array, accepting only decimal digit characters ['0','9'], and encoding each digit in an octet as [0,9].
BinaryStringCodec<T>	getLaxDecoder() Gets a BinaryStringCodec that decodes invalid characters to ? characters instead of throwing an exception.
static <T> BinaryStringCodec<T>	getStandardCodec() Gets the standard BinaryStringCodec.

Method Detail

getStandardCodec

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

Gets the standard BinaryStringCodec.

Returns:

BinaryStringCodec

getLaxDecoder

public BinaryStringCodec<T> getLaxDecoder()

Gets a BinaryStringCodec that decodes invalid characters to ? characters instead of throwing an exception. Its encodeString() method does nothing useful. 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 decimal digit characters ['0','9'], and encoding each digit in an octet as [0,9]. Sets indicators 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 any character of the given String is not a decimal digit

encodeString

public byte[] encodeString(String string)

Encodes a String of characters to a byte array, accepting only decimal digit characters ['0','9'], and encoding each digit in an octet as [0,9].

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 any character of the given String is not a decimal digit

encodeCharArray

public byte[] encodeCharArray(char[] chars)

Encodes an array of characters to a byte array, accepting only decimal digit characters ['0','9'], and encoding each digit in an octet as [0,9].

Parameters:

chars - the character array to be encoded to a byte array

Returns:

the encoded byte array

Throws:

UnsupportedDigitException - if any character of the given String is not a decimal digit

decodeString

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

Decodes a String of characters from a byte array, taking length values from octets, rejecting any value that isn't in range [0,9], and decoding to characters ['0','9'].

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 [0,9]

decodeString

public String decodeString(byte[] encoded)

Decodes a String of characters from a byte array, taking length values from octets, rejecting any value that isn't in range [0,9], and decoding to characters ['0','9'].

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 [0,9]
