Class TerminalFactorySpi
Service providers that want to write a new implementation should define
a concrete subclass of TerminalFactorySpi with a constructor that takes
an Object
as parameter. That class needs to be registered
in a Provider. The engine
type is
TerminalFactory
.
Service providers also need to implement subclasses of the abstract classes
CardTerminals, CardTerminal, Card,
and CardChannel.
For example:
file MyProvider.java: package com.somedomain.card; import java.security.Provider; public class MyProvider extends Provider { public MyProvider() { super("MyProvider", 1.0d, "Smart Card Example"); put("TerminalFactory.MyType", "com.somedomain.card.MySpi"); } } file MySpi.java package com.somedomain.card; import javax.smartcardio.*; public class MySpi extends TerminalFactoySpi { public MySpi(Object parameter) { // initialize as appropriate } protected CardTerminals engineTerminals() { // add implementation code here } }

-
TerminalFactorySpi
protected TerminalFactorySpi()Constructs a new TerminalFactorySpi object.This class is part of the service provider interface and not accessed directly by applications. Applications should use TerminalFactory objects, which can be obtained by calling one of the TerminalFactory.getInstance() methods.
Concrete subclasses should define a constructor that takes an
Object
as parameter. It will be invoked when an application calls one of the TerminalFactory.getInstance() methods and receives theparams
object specified by the application.
