Class TerminalFactorySpi

java.lang.Object
javax.smartcardio.TerminalFactorySpi

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 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
      }
 }

  • Constructor Details

    • 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 the params object specified by the application.
