Constructor Detail

CommandAPDU

public CommandAPDU(byte[] buffer)
Creates a new re-usable command APDU and initializes it with the given buffer. The internal buffer's length is set to the length of the buffer passed.
Parameters:
buffer - the byte array to be used for holding the APDU
See Also:
APDU.getLength()

CommandAPDU

public CommandAPDU(byte[] buffer,
                   int length)
            throws java.lang.IndexOutOfBoundsException
Creates a new re-usable command APDU and initializes it with the given buffer. The buffer is assumed to hold an APDU. The length of the internally buffered APDU is set to length.
Parameters:
buffer - the byte array to be used for holding the APDU
length - the length of the APDU currently in the buffer
Throws:
java.lang.IndexOutOfBoundsException - length exceeds the size of the array bytes.
