Security token for this slot.




Constructor Detail
CardSlot
public CardSlot(CardDevice device, int slot, SecurityToken token) throws IOException(Code)
Creates card slot on the specified device.
Parameters:
  device - Card device for which the slot is created
Parameters:
  slot - Local device slot number
Parameters:
  token - Security token for this slot
throws:
  IOException - If slot creation failed.




Method Detail
closeSlot
public void closeSlot() throws IOException(Code)
Closes the slot in case of error. device.closeSlot usually does nothing. Used for socket-like 'devices'.
throws:
  IOException - If something fails.



getATR
public byte[] getATR()(Code)
Gets ATR bytes from the device. ATR bytes.



getCardSessionId
public int getCardSessionId()(Code)
Returns the card session identifier. This number is different for different card sessions. the card session identifier or -1 when slot is closed



getDevice
protected CardDevice getDevice()(Code)
Gets device of this slot. For using in derived classes. Slot device



getSlotNumber
public int getSlotNumber()(Code)
Gets local device slot number. Local slot number.



initACL
public void initACL()(Code)
Initializes ACL for the slot.



initConnection
public boolean initConnection() throws IOException(Code)
Makes sure that slot is ready for connection. true if this is first connection to inserted card
throws:
  IOException - If something fails.



isAlive
public boolean isAlive()(Code)
Checks if the the connection is still live or not. It is a public wrapper for doIsAlive. Also checks if a card was changed. Slot must not be locked. true if the connection is alive



isSAT
public boolean isSAT() throws IOException(Code)
Checks if this slot is SAT slot. SAT check result
throws:
  IOException - If an error occured.



lockSlot
public void lockSlot() throws IOException(Code)

throws:
  IOException - If something fails.



unlockSlot
public void unlockSlot()(Code)
Ends operations with the slot. IOException is ignored.



xferData
public int xferData(byte[] request, byte[] response) throws IOException(Code)
Performs data transfer to the device slot. It must be called where slot is locked.
Parameters:
  request - Request APDU bytes
Parameters:
  response - Response bytes Length of response
throws:
  IOException - If a data transfer failed orthe card was changed.
