APDU buffer access

Question

Let’s say that I want to define the method that handles the command APDU that is located in the APDU buffer.
I do not want for the method to have input parameter equals APDU. Instead I want the method to be without any input parameter. The method itself must be able to read the APDU buffer. Is it possible and if yes how? I saw the BACAccelerator class that has that kind of definition that suits me:
      * Unwraps (verify and decrypt) the command APDU located in the APDU buffer.
      * The command buffer has to be filled by the APDU.setIncomingAndReceive()
      * method beforehand. The verified and decrypted command data get placed at
      * the start of the APDU buffer.
     public short unwrapAPDU() throws BACAcceleratorException {
          return ((short) 0);
     }

Answer 1

there is probably an application specific buffer that the APDU is copied into. This may be a field of the class that is accessed. This is just a guess though.
