CardSimulationAdapter - Reference Documentation
Class to control a card simulation adapter that forwards APDUs to a script implementation
Index of Methods
Constructor
Prototype
CardSimulationAdapter(String adapter, String parameter)
Description
Create a new card simulation adapter.
Currently only the JCOP Simulation adapter is available. It is configured as adapter name "JCOPSimulation" with the port number as parameter.
Arguments
| Type | Name | Description |
|---|---|---|
String
|
adapter | Name of the simulation adapter |
String
|
source | The parameter used to initialise the adapter |
Exceptions
| Name | Value | Description |
|---|---|---|
| GPError | GPError.ARGUMENTS_MISSING | Too few arguments in call |
| GPError | GPError.INVALID_ARGUMENTS | Too many arguments in call |
| GPError | GPError.INVALID_TYPE | Type of argument is invalid for call |
Example
var sa = new CardSimulationAdapter("JCOPSimulation", "8050");
setSimulationObject()
Prototype
void setSimulationObject(Object simulation)
Description
Set the object that receives reset() and processAPDU() calls from the card simulation adapter.
The simulation object must implement the following methods:
void reset(Number coldOrWarm); ByteString processAPDU(ByteString capdu);The parameter coldOrWarm allows to differentiate between a cold and a warm reset. This parameter is currently always 0 (cold reset).
The parameter capdu contains the raw command APDU, including CLA, INS, P1, P2 and conditionally the Lc, Command Data and Le field.
The processAPDU() method must return the response APDU as ByteString object, with the conditional response data field and the trailer bytes SW1/SW2.
Arguments
| Type | Name | Description |
|---|---|---|
Object
|
simulation | The object that implements the card simulation |
Return
|
Exceptions
| Name | Value | Description |
|---|---|---|
| GPError | GPError.ARGUMENTS_MISSING | Too few arguments in call |
| GPError | GPError.INVALID_ARGUMENTS | Too many arguments in call |
| GPError | GPError.INVALID_TYPE | Type of argument is invalid for call |
Example
// Create a very simple card simulator
var simulationObject = new Object();
// The simulator needs a processAPDU method
simulationObject.processAPDU = function(capdu) {
print("Received APDU: " + capdu);
var rapdu = capdu.concat(new ByteString("9000", HEX));
return rapdu;
}
// The simulator needs a reset method
simulationObject.reset = function(type) {
print("Reset type: " + type);
var atr = new ByteString("3B600000", HEX);
return atr;
}
sa.setSimulationObject(simulationObject);
start()
Prototype
void start()
Description
Starts the simulator adapter.
If the adapter is already running, it is stopped first.
Return
|
Exceptions
| Name | Value | Description |
|---|---|---|
| GPError | GPError.INVALID_ARGUMENTS | Too many arguments in call |
Example
sa.start();
var card = new Card("JCOPSimulation");
var atr = card.reset(Card.RESET_COLD);
print(atr);
assert(atr.toByteString().toString(HEX) == "3B600000");
var rapdu = card.sendApdu(0x00, 0x10, 0x01, 0x02, new ByteString("1234", HEX), [0x9000]);
assert(rapdu.toString(HEX) == "00100102021234");
stop()
Prototype
void stop()
Description
Stops the simulator adapter.
Return
|
Exceptions
| Name | Value | Description |
|---|---|---|
| GPError | GPError.INVALID_ARGUMENTS | Too many arguments in call |
Example
sa.stop();
