Method Detail

data

public byte[] data()
Gets the data fields of the APDU.
Returns:
a byte array containing the APDU data field

sw

public final int sw()
Gets the value of SW1 and SW2 as a short integer. It is computed as: (((sw1<<8)&0xFF00) | (sw2&0xFF)).
Returns:
The value (((sw1<<8)&0xFF00) | (sw2&0xFF)) as integer.

sw1

public final byte sw1()
Gets the value of SW1 as a byte.
Returns:
The value of SW1

sw2

public final byte sw2()
Gets the value of SW1 as a byte.
Returns:
The value of SW2
