Constructor Detail

CHVControl

public CHVControl(java.lang.String prompt,
                  java.lang.String applicationID,
                  java.lang.String passwordEncoding,
                  int passwordOffset,
                  CardTerminalIOControl ioControl)

The constructor setting all fields.

Parameters:

prompt - a string to be displayed to ask the user to enter his password

applicationID - an identification to tell the user which application needs CHV

passwordEncoding - identification of the encoder to convert the password String to a byte array

passwordOffset - offset of the password within the body of the verify APDU

ioControl - parameters for keyboard input

CHVControl

public CHVControl(java.lang.String prompt,
                  int chvNumber,
                  java.lang.String passwordEncoding,
                  int passwordOffset,
                  CardTerminalIOControl ioControl)

The constructor setting all fields.

Parameters:

prompt - a string to be displayed to ask the user to enter his password

chvNumber - number of CHV to be requested from the user

passwordEncoding - identification of the encoder to convert the password String to a byte array

passwordOffset - offset of the password within the body of the verify APDU

ioControl - parameters for keyboard input

Method Detail

prompt

public java.lang.String prompt()

Returns:

the prompt string

applicationID

public java.lang.String applicationID()

Get the application ID string.

The application ID gives the user information on the application he is expected to give card holder verification for.

Returns:

the applicateion id string.

chvNumber

public int chvNumber()

Get the chvNumber for which a CHV is required.

Returns:

CHV number

passwordEncoding

public java.lang.String passwordEncoding()

Get the password encoding.

The password encoding defines the method to obtain the byte array from the String read from the user. The default is to use the default encoding of the machine.

Returns:

password encoding information

passwordOffset

public int passwordOffset()

Offset of the password in the body of the command APDU

Returns:

the offset

ioControl

public CardTerminalIOControl ioControl()

Get the I/O control parameters.

Returns:

a reference to a CardTerminalIOControl instance
