7） 抽象扫描缓冲区工厂：BufferFactory.Java（使用抽象工厂方法模式产生缓冲区对象）
//Source file: d:\\JAccidenceAnalyse\\Buffer\\BufferFactory.Java

package JAccidenceAnalyse.Buffer;

public interface BufferFactory {

  /**
   * @return JAccidenceAnalyse.Buffer.ScanBuffer
   * @roseuid 3D9BB6F0003E
   */
  public ScanBuffer createScanBuffer(int size);

  /**
   * @return JAccidenceAnalyse.Buffer.InputBuffer
   * @roseuid 3D9BB7090062
   */
  public InputBuffer createInputBuffer(int size);
}
8） 缓冲区工厂：ConcreteScanBufferFactory.Java（实现了抽象工厂）
//Source file: d:\\JAccidenceAnalyse\\Buffer\\ConcreteScanBufferFactory.Java

package JAccidenceAnalyse.Buffer;

public class ConcreteScanBufferFactory
    implements BufferFactory {

  /**
   * @roseuid 3D9BBA19006A
   */
  public ConcreteScanBufferFactory() {
    System.out.println("[INFOR]缓冲区工厂已经建立!");
  }

  /**
   * @return JAccidenceAnalyse.Buffer.ScanBuffer
   * @roseuid 3D9BAC01004E
   */
  public ScanBuffer createScanBuffer(int size) {
    System.out.println("[INFOR]创建扫描缓冲区!");
    return new ScanBuffer(size);
  }

  /**
   * @return JAccidenceAnalyse.Buffer.InputBuffer
   * @roseuid 3D9BB6050267
   */
  public InputBuffer createInputBuffer(int size) {
