Method Detail

check_buffer

private byte check_buffer(Resizable_buffer b,
                          byte count)

Check if the buffer b contains the expected data-check pattern. The host fills the buffer with the consecutive numbers from 0 to 255, repeated as often as necessary over all arguments it sends to the card. This method checks if this pattern arrived here in the applet.

Parameters:

b - buffer to check

count - start value for the first byte of the buffer

Returns:

the next expected byte contents for the first byte of the next buffer to check

Throws:

ISOException - with value Response_status.OV_TEST_FAILED_00 | 0x01 in case the buffer contains unexpected data.

fill_buffer

private byte fill_buffer(Resizable_buffer b,
                         byte count)

Fill the buffer with the data-check pattern. The data-check pattern consists of the consecutive numbers from 0 to 255, repeated as often as encessary over all arguments or results.

Parameters:

b - buffer to fill

count - start value for the first byte of b

Returns:

the first byte for the next buffer

check

public void check(Resizable_buffer a1,
                  Resizable_buffer a2,
                  Resizable_buffer a3,
                  Resizable_buffer a4,
                  Resizable_buffer a5,
                  Resizable_buffer b1,
                  Resizable_buffer b2,
                  Resizable_buffer b3,
                  Resizable_buffer b4,
                  Resizable_buffer b5)

Check and fill all 10 buffers. This method checks if all argument buffers contain the data-check pattern and writes this pattern into the result buffers.

Parameters:

a1 - argument buffer

a2 - argument buffer

a3 - argument buffer

a4 - argument buffer

a5 - argument buffer

b1 - result buffers

b2 - result buffers

b3 - result buffers

b4 - result buffers

b5 - result buffers
