Method Summary

Methods

Modifier and Type	Method and Description
String	decodeString(byte[] encoded) Decodes a String of characters from a byte array, expecting 7-bit packed format of GSM7 characters, deciding whether there are 1 or 8 bits used in the last octet based on whether its index is a multiple of 7 and the 7 bits are all 0.
String	decodeString(byte[] encoded, StringIndicators indicators) Decodes a String of characters from a byte array, expecting 7-bit packed format of GSM7 characters, using the given indicators to distinguish whether 1 or 8 bits are used in the last octet.
byte[]	encodeString(String string) Encodes a String of characters to a byte array, accepting only GSM7 characters and encoding them in 7-bit packed format.
byte[]	encodeString(String string, StringIndicators indicators) Encodes a String of characters to a byte array, accepting only GSM7 characters and encoding them in 7-bit packed format.
GSM7PACKEDStringCodec<T>	getLaxDecoder() Gets the standard GSM7PACKEDStringCodec.
static <T> GSM7PACKEDStringCodec<T>	getStandardCodec() Gets the standard GSM7PACKEDStringCodec.

Method Detail

getStandardCodec

public static <T> GSM7PACKEDStringCodec<T> getStandardCodec()

Gets the standard GSM7PACKEDStringCodec.

Returns:

GSM7PACKEDStringCodec

getLaxDecoder

public GSM7PACKEDStringCodec<T> getLaxDecoder()

Gets the standard GSM7PACKEDStringCodec. This method is required by interface StringCodec, but it needn't return a different GSM7PACKEDStringCodec as all encodings can be decoded.

Specified by:

getLaxDecoder in interface StringCodec<T>

Returns:

GSM7PACKEDStringCodec

encodeString

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

Encodes a String of characters to a byte array, accepting only GSM7 characters and encoding them in 7-bit packed format. Sets indicators to assist decoding by this or 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 GSM7 character

encodeString

public byte[] encodeString(String string)

Encodes a String of characters to a byte array, accepting only GSM7 characters and encoding them in 7-bit packed format.

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 GSM7 character

decodeString

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

Decodes a String of characters from a byte array, expecting 7-bit packed format of GSM7 characters, using the given indicators to distinguish whether 1 or 8 bits are used in the last octet.

Specified by:

decodeString in interface StringCodec<T>

Parameters:

encoded - the byte array to be decoded to a String

indicators - indicator values needed for decoding

Returns:

the decoded String

decodeString

public String decodeString(byte[] encoded)

Decodes a String of characters from a byte array, expecting 7-bit packed format of GSM7 characters, deciding whether there are 1 or 8 bits used in the last octet based on whether its index is a multiple of 7 and the 7 bits are all 0.

Specified by:

decodeString in interface StringCodec<T>

Parameters:

encoded - the byte array to be decoded to a String

Returns:

the decoded String
