Question on apdu.getBuffer() and apdu.setIncomingAndReceive()

Hi,

I have some questions on methods of APDU class.

When we want to receive APDU, we first create a buffer to hold APDU command bytes.

For example: byte[] buf=apdu.getBuffer();

All of the APDU bytes we receive and send are all stored in this byte array.

Another method :apdu.setIncomingAndReceive() is used to recieve APDU and put it in buf[].

So if we want to handle APDU,we should first call this method. Otherwise the APDU in buf[] is still the last reveived APDU but not the current APDU we want to receive.

And we should call this method wherever we want to recieve current APDU.

Am I right?
