Constructor and Description
CommandApdu(int cla, int ins, int p1, int p2) Constructs a case 1 command APDU just from the 4 header bytes
CommandApdu(int cla, int ins, int p1, int p2, byte[] data) Constructs a case 3 APDU If data is null or empty, it constructs a case 1 APDU.
CommandApdu(int cla, int ins, int p1, int p2, byte[] data, java.lang.Integer ne) Constructs a case 4 APDU from the four header bytes, command data, and expected response data length.
CommandApdu(int cla, int ins, int p1, int p2, java.lang.Integer ne) Constructs a case 2 APDU If ne is null it is encoded as case 1 APDU

Constructor Detail

CommandApdu

public CommandApdu(int cla,
                   int ins,
                   int p1,
                   int p2)

Constructs a case 1 command APDU just from the 4 header bytes

Parameters:

cla - class octet of command APDU

ins - INS octet of command APDU

p1 - P1 octet of command APDU

p2 - P2 octet of command APDU

CommandApdu

public CommandApdu(int cla,
                   int ins,
                   int p1,
                   int p2,
                   java.lang.Integer ne)

Constructs a case 2 APDU If ne is null it is encoded as case 1 APDU

Parameters:

cla - class octet of command APDU

ins - INS octet of command APDU

p1 - P1 octet of command APDU

p2 - P2 octet of command APDU

ne - number of expected length

CommandApdu

public CommandApdu(int cla,
                   int ins,
                   int p1,
                   int p2,
                   byte[] data)

Constructs a case 3 APDU If data is null or empty, it constructs a case 1 APDU. Command data length Nc is derived from the byte array of data param

Parameters:

cla - class octet of command APDU

ins - INS octet of command APDU

p1 - P1 octet of command APDU

p2 - P2 octet of command APDU

data - command data

CommandApdu

public CommandApdu(int cla,
                   int ins,
                   int p1,
                   int p2,
                   byte[] data,
                   java.lang.Integer ne)

Constructs a case 4 APDU from the four header bytes, command data, and expected response data length. Command data length Nc is derived from the byte array of data param

If data is empty or null and/or ne is null, APDU is encoded as case 1, 2, or 3 per ISO 7816 respectively.

Parameters:

cla - CLA byte

ins - INS byte

p1 - P1 byte

p2 - P2 byte

data - data octet string if data is null it is encoded as case 1 or 3 respectively

ne - number of expected bytes in response. if ne is null it is encoded as case 1 or 3 respectively ne = 0 is encoded as wildcard (short or extended) ne = AbstractApdu.EXPECTED_LENGTH_WILDCARD_SHORT or ne = AbstractApdu.EXPECTED_LENGTH_WILDCARD_EXTENDED it is encoded as short or extended wildcard respectively

Throws:

java.lang.IllegalArgumentException - thrown in case of invalid parameter values
