Detailed Description

A response APDU as defined in ISO/IEC 7816-4. It consists of a conditional body and a two byte trailer. This class does not attempt to verify that the APDU encodes a semantically valid response.

Instances of this class are immutable. Where data is passed in or out via byte arrays, defensive cloning is performed.

Constructor & Destructor Documentation

fr.redbilled.pcscforjava.ResponseAPDU.ResponseAPDU ( byte[]  apdu)

Constructs a ResponseAPDU from a byte array containing the complete APDU contents (conditional body and trailed).

Note that the byte array is cloned to protect against subsequent modification.

Parameters:
apduthe complete response APDU
Exceptions:
NullPointerExceptionif apdu is null
IllegalArgumentExceptionif apdu.length is less than 2

Member Function Documentation

boolean fr.redbilled.pcscforjava.ResponseAPDU.equals ( Object  obj)

Compares the specified object with this response APDU for equality. Returns true if the given object is also a ResponseAPDU and its bytes are identical to the bytes in this ResponseAPDU.

Parameters:
objthe object to be compared for equality with this response APDU
Returns:
true if the specified object is equal to this response APDU

Here is the caller graph for this function:

byte [] fr.redbilled.pcscforjava.ResponseAPDU.getBytes ( )

Returns a copy of the bytes in this APDU.

Returns:
a copy of the bytes in this APDU.

Definition at line 137 of file ResponseAPDU.java.

byte [] fr.redbilled.pcscforjava.ResponseAPDU.getData ( )

Returns a copy of the data bytes in the response body. If this APDU as no body, this method returns a byte array with a length of zero.

Returns:
a copy of the data bytes in the response body or the empty byte array if this APDU has no body.

Definition at line 96 of file ResponseAPDU.java.

int fr.redbilled.pcscforjava.ResponseAPDU.getNr ( )

Returns the number of data bytes in the response body (Nr) or 0 if this APDU has no body. This call is equivalent to getData().length.

Returns:
the number of data bytes in the response body or 0 if this APDU has no body.

Definition at line 85 of file ResponseAPDU.java.

int fr.redbilled.pcscforjava.ResponseAPDU.getSW ( )

Returns the value of the status bytes SW1 and SW2 as a single status word SW. It is defined as (getSW1() << 8) | getSW2().

Returns:
the value of the status word SW.
