analyseStatus

public void analyseStatus(int status,
                          byte command,
                          java.lang.Object context)
                   throws CardServiceException
Analyses the status of a smartcard's response to a command. If the command completed successfully, the method returns without further action. If an error occurred, an exception is thrown. This method uses indicatesError to determine whether an exception has to be thrown.
Specified by:
analyseStatus in interface MFCCodes
Parameters:
status - the status word returned by the smartcard
command - the INStruction sent to the smartcard
context - the context in which the command was issued
Throws:
CardServiceException - iff the status indicates an error
See Also:
indicatesError(int)

indicatesError

public boolean indicatesError(int status)
Checks whether the response status indicates an error. If so, true is returned.
Specified by:
indicatesError in interface MFCCodes
Parameters:
status - the status returned by the smartcard
Returns:
false if the command completed successfully, true otherwise
