| * The TerminalFactorySpi class defines the service provider interface. |
| * Applications do not access this class directly, instead see |
| * {@linkplain TerminalFactory}. |
| * |
| * <P>Service providers that want to write a new implementation should define |
| * a concrete subclass of TerminalFactorySpi with a constructor that takes |
| * an <code>Object</code> as parameter. That class needs to be registered |
| * in a {@linkplain java.security.Provider}. The engine |
| * {@linkplain java.security.Provider.Service#getType type} is |
| * <code>TerminalFactory</code>. |
| * Service providers also need to implement subclasses of the abstract classes |
| * {@linkplain CardTerminals}, {@linkplain CardTerminal}, {@linkplain Card}, |
| * and {@linkplain CardChannel}. |
| * |
| * <p>For example: |
| * <pre><em>file MyProvider.java:</em> |
| * |
| * 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"); |
| * } |
| * } |
| * |
| *<em>file MySpi.java</em> |
| * |
| * 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 |
| * } |
| * } |
