 public abstract class TerminalFactorySpi extends Object The TerminalFactorySpi class defines the service provider interface. Applications do not access this class directly, instead see TerminalFactory.Service providers that want to write a new implementation should define a concrete subclass of TerminalFactorySpi with a constructor that takes an Objectas parameter. That class needs to be registered in a Provider. The engine type isTerminalFactory. 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 } }- Since:

Constructor Detail- 
TerminalFactorySpiprotected 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 Objectas parameter. It will be invoked when an application calls one of the TerminalFactory.getInstance() methods and receives theparamsobject specified by the application.
