- public final class PassThruCardServiceFactory
- extends OCF11CardServiceFactory
A factory for creating low level card services for any smartcard.
The only service this factory can create is PassThruCardService,
which is available for all smartcards. This class serves as an example
for implementing a simple card service factories, and provides a
"quick start" for people who want to become familiar with smartcards
and the OpenCard Framework.
To use the service instantiated by this factory, add
opencard.opt.util.PassThruCardServiceFactory to the
attribute OpenCard.services in your opencard.properties
file, preferrably as the last entry.

PassThruCardServiceFactory
public PassThruCardServiceFactory()
- Instantiates a new factory for low level card services.
knows
public final boolean knows(opencard.core.terminal.CardID cardID)
- Tests whether this factory supports a given smartcard.
The smartcard is identified by it's ATR (Answer To Reset), which is
encapsulated in a CardID object. Since all smartcards can
receive APDUs and send responses to them, this factory supports all
cards. If a smartcard is supported, the card services this factory
is able to instantiate can be obtained using cardServiceClasses.
- Parameters:
cardID
- the ATR of the smartcard to test for- Returns:
- true, since this factory supports all smartcards
- Overrides:
- knows in class OCF11CardServiceFactory

cardServiceClasses(opencard.core.terminal.CardID)
cardServiceClasses
public final java.util.Enumeration cardServiceClasses(opencard.core.terminal.CardID cardID)
- Returns an enumeration of known card service classes.
Known classes are those that can be instantiated by this
factory for the given smartcard. To check whether a factory is able
to instantiate any service at all for that smartcard, knows
can be invoked. Since this factory supports all smartcards, and can
only instantiate one service, this method returns a constant value.
- Parameters:
cardID
- the ATR of the smartcard to test for- Returns:
- an enumeration holding PassThruCardService.class
as it's only element
- Overrides:
- cardServiceClasses in class OCF11CardServiceFactory
