class ExclusiveTransmitCardConnection(CardConnectionDecorator):

Constructor: ExclusiveTransmitCardConnection(cardconnection)

Method __init__ Construct a new card connection decorator.
Method lock Lock card with SCardBeginTransaction.
Method transmit Gain exclusive access to card during APDU transmission for if this decorator decorates a PCSCCardConnection.
Method unlock Unlock card with SCardEndTransaction.
